Define it.Pointer is a variable which stores the address of other variables which hold some value in it. Directly pointer is used to point values of variables indirectly. We can manipulate its values.2) What is a dangling pointer in C?Dangling pointer is a pointer which does not point to a valid object of the appropriate type. It appears when a pointer is in the stack but not in the memory in a heap. Char *p =NULL; A dangling pointer attempt to deallocate without allocating space will result in a segmentation fault.Dangling pointers arise during object destruction, when an object that has an incoming reference is deleted or deallocated, without changing the data of the pointer, so that the pointer points to the memory location of the deallocated memory.3) What is a memory leak in a heap?When there is a space area in a heap, but no variable is in the stack pointing to that memory.4) What is a data type?Data Type defines the type of value which are allocated by us to a variable and have a range in between we assign values. E.g., "Int" it is a data type which able to store data between "-32768 to +32768" in C.5) What is the size of the integer data type?Size of it is 2 Byte or 4 Byte.6) What is malloc?Allocates requested size of bytes and returned a pointer first byte of allocated space. Malloc is using for dynamic memory allocation.Syntax:ptr = (cast-type*) malloc(byte-size) 7) What is a string?A string is a sequence of characters. It can be defined using the array or by using String header file.8) "/0" in a string?This symbol shows the ending of the string.E.g. char a[] = {"s","e","t","/0"};.9) What is recursion?The process by which a method calls itself directly or indirectly, again and again, is called recursion and the corresponding function.10) What is the difference between a pre-increment operator and post-increment operator?Pre-increment operator used incrementing the variable value by one before assigning the cost to the variable. Post-increment operator use to incrementing the variable value by one after assigning the value to the variable.11) What are the key features or characteristics OFC language?ReliabilityPortabilityFlexibilityInteractivityModularityEfficiency and Effectiveness12) What is embedded C?Embedded C is the extension of C programming language.Embedded C is used to develop microcontroller-based applications.Embedded C includes features not available in standard C like fixed-point arithmetic, named address spaces, and necessary I/O hardware addressing.Cell phones, MP3 players are some example of embedded systems in which integrated C is used to program and control these devices.13) Which level is C language belonging?C language is belonging to middle-level language. C language behaves as a bridge between machine level (low level) languages and high-level languages.C language is more user-friendly than machine level languages. And, C language does not support all the concepts that high-level languages offer. So, C programming language called as middle-level language.14) What is the difference between structured oriented, object-oriented and non-structure oriented programming language?Structured oriented programming language -In this type of language, large codes fragmented into small programs called functions.The main focus is on procedures and functions that operate on valuesData moves without any restrictions around the systems from one procedure to anotherProgram structure follows "Top-Down Approach."Example: C, Pascal, ALGOL, and Modula-2Object-oriented programming language -In this type of language, programs fragmented into objectsThe main focus is on the data/values that are manipulating and not on the procedures or functions.Data is hidden from functions and cannot access by external functionsProgram structure follows the "Bottom UP Approach."Example: C++, and C# (C sharp)Non-structure oriented programming language -There is no specific structure rule for programming this language.Example: BASIC, COBOL, FORTRAN14) What is modifier in C?Modifiers derive the space to allocate for a variable.Modifiers are fixed with basic data types to modify (either increase or decrease) the amount of storage allocated to a variable.For example, storage requirements for int data type are 4 bytes for a 32-bit processor. We can increase range by using long int data type which is 8 byte. We can decrease the range by using short int which is 2 byte.15) What is the difference between variable declaration and variable definition in C?Variable declaration tells the compiler about data type and size of the variable. Whereas, variable definition allocates memory to the variableVariable can be declared many times in a program. But, the definition can happen only one time for a variable in a program.Variable declaration is for assignment of properties and identification to a variable. Whereas, a variable definition is for assignments of storage space to a variableCognizant OOPs Interview Questions1) What are virtual Functions?In object-oriented programming, in languages such as C++, and Object Pascal, a virtual function or virtual method is an inheritable and overrideable function or method for which dynamic dispatch facilitated. This concept is an essential part of the (runtime) polymorphism portion of object-oriented programming (OOP).2) What is overloading in OOPs?Overloading is a process used to avoid redundant code where the same method name used multiple times but with a different set of parameters. The actual method that gets called during runtime is resolved at compile time, thus avoiding runtime errors.3) What is overriding?In any object-oriented programming, Overriding is a process that allows a child class or subclass to provide a specific implementation of functions that is already provided by one of its super-classes or parent classes.4) What is polymorphism?By using the ability of polymorphism an object can take on multiple types. The frequent use of polymorphism occurs when a parent class refers to an object of the child class. The Java object that can pass more than one IS-A test is polymorphic.5) What is data abstraction?In oops, abstraction is one of three main principles (along with encapsulation and inheritance). Through the process of abstraction, a programmer hides all but the relevant data about an object to reduce complexity and increase efficiency.6) What is encapsulation?Encapsulation is one of the primary concepts in object-oriented programming. It describes the idea of combining data in a single class and methods that work on that data, e.g., a class which is a blueprint in java. This concept is also often used to preserve the internal state, of an object from the outside.7) What is Inheritance in java?In object-oriented programming, inheritance helps new objects to take on the properties of old objects. A class that uses for inheritance is called a base class or superclass. A class that inherits data from a base class is called a subclass or derived class8) What is the constructor?A constructor is a method which is used to initialize a newly created object and is called just after when memory allocated to the object. It can be used to implement the objects to desired values or default values at the time of object creation.9) What is the destructor?A destructor used when the initialized object is destructing it called automatically during the destruction of an object. It helps in recovering the heap space and remove files.Cognizant Data structure Interview Questions1) What is a Data Structure?Data Structure is a process in which management or organization of data that enable a more efficient way to organize the data.2) What have linked lists?A linked list is a set of ordered data and each of its previous nodes connected to its succeeding node. It is like an array but more efficient then array because we can insert or delete data in between the nodes.3) Is the array of data structure?Yes, because it also handles the data in a structured way.4) Define a binary search Tree?It is also known as ordered or sorted binary tree. It keeps there nodes or keys in sort form, and the root node of BST is bigger than the left node and smaller than the right node.5) What is a Binary Tree in the data structure?A binary tree is part of a data structure that has two sub-nodes, a right node, and a left node. In programming, binary trees are an advanced version of the linked list.6) What is the dissimilarity between Push and Pop methods of the stack?Pushing and popping applies to the way data is stored and fetched from a stack. A push method denotes data being added to it, meaning information is being "pushed" in the stack. On the other hand, a pop method denotes data retrieval/fetch, and in particular, refers to the first data is being fetched.7) What is the dissimilarity between a stack and the array?A stack base on LIFO pattern. It means that data access follows a sequential process wherein the last data to be entered when the first one deleted. Arrays do not follow a particular order and instead can access by referring to the indexed element within the array.8) What are doubly linked Lists?Doubly linked lists are a particular part of linked list wherein traversal across the data elements can be done in any directions. This is possible by having two links in every node, one that connects to the next node and another one that links to the previous node.9) What is a queue data structure?A Queue is a data structure which is linear and follows a fixed order in which the operations occur. The order is always First In First Out (FIFO). An excellent example of a queue is any queue of the customer for a resource where the customer that came first served first. The difference between stacks and queues is while deleting.10) What is a stack data structure?Basic features of Stack are an ordered list of the similar data type. The stack is LIFO (Last In First Out) data structure, or we can say FILO (First In Last Out) data structure. Push () method is used to insert/enter new elements into the Stack and pop() method is used to remove/delete an element from the stack.11) What is a graph in the data structure?A graph shows a representation of a set of objects/nodes where some pairs of object/nodes are connected by links/connection. The interconnection of objects are represented by points termed as vertices, and the links that connect the vertices are called edges.12) What is a priority queue?A priority queue is an abstracted data type which is like a queue or stack data structure, but where additionally each element has a "priority" associated with it. In a priority queue, an element with high priority is served before an element with low priority.13) Show the time complexity of the linked list during insertion?The time complexity of insertion/deletion in a singly linked list depends upon the position where you want to perform them. For example, if you want to insert an element at the end of the linked list, then you have to traverse/travel the entire list, and hence the complexity will be O(n).Cognizant Programming Questions1) Write a program to reverse any number.This code below is written in Java.package javaapplication6; import java.util.Scanner; public class JavaApplication6 { public static void main(String[] args) { int i, temp, sum=0, n; Scanner sc = new Scanner(System.in); n=sc.nextInt(); temp=n; while(n>0) { int r = n%10; sum = sum*10+r; n = n/10; } System.out.println("Reverse of Number is:-" +sum); if(temp==sum) { System.out.println("Palindrom"); } else { System.out.println("Not Palindrom"); } } } 2) Write a program to find out some of the digits of the given number.package javaapplication6; import java.util.Scanner; public class JavaApplication6 { public static void main(String[] args) { int i, temp, sum=0, n; Scanner sc = new Scanner(System.in); n=sc.nextInt(); temp=n; while(n>0) { int r = n%10; sum = sum+r; n = n/10; } System.out.println("Reverse of Number is:-" +sum); } } 3) Write a program to find out the power of a number.package javaapplication6; import java.util.Scanner; public class JavaApplication6 { public static void main(String[] args) { int result=1, n; Scanner sc = new Scanner(System.in); System.out.println("the Exoponent is:- "); n=sc.nextInt(); System.out.println("the base is:- "); int base = sc.nextInt(); while (n != 0) { result *= base; --n; } System.out.println("Power of Number is:-" +result); } } 4) Write a program to add two numbers without using the addition operator.package javaapplication6; import java.util.Scanner; public class JavaApplication6 { static int Add(int x, int y) { while (y != 0) { int carry = x & y; x = x ^ y; y = carry << 1; } return x; } public static void main(String arg[]) { Scanner sc = new Scanner(System.in); System.out.println("First value is:- "); int a=sc.nextInt(); System.out.println("Second value is:- "); int b=sc.nextInt(); System.out.println("Sum of both digits:- "+Add(a, b)); } } 5) Write a program to subtract two numbers without using a subtraction operator.package javaapplication6; import java.util.Scanner; public class JavaApplication6 { static int Add(int x, int y) { while (y != 0) { int borrow = ~ x & y; x = x ^ y; y = borrow << 1; } return x; } public static void main(String arg[]) { Scanner sc = new Scanner(System.in); System.out.println("First value is:- "); int a=sc.nextInt(); System.out.println("Second value is:- "); int b=sc.nextInt(); System.out.println("Sum of both digits:- "+Add(a, b)); } } 6) Write a program to show largest among three numbers using binary minus operator.package javaapplication9; import java.util.Scanner; public class JavaApplication9 { public static void main(String[] args) { Scanner s = new Scanner(System.in); int a = s.nextInt(); int b = s.nextInt(); int c = s.nextInt(); if(a-b>0 && a-c>0) System.out.println("Greatest is a :-"+a); else if(b-c>0) System.out.println("\nGreatest is b :-"+b); else System.out.println("\nGreatest is b :-"+c); } } 7) Write a program to show the largest among three numbers using conditional operator.package javaapplication9; import java.util.Scanner; public class JavaApplication9 { public static void main(String[] args) { Scanner s = new Scanner(System.in); int a = s.nextInt(); int b = s.nextInt(); int c = s.nextInt(); int big = a > b ?

Out of the two, one program should compile successfully to go for next round of interview.Note: The candidate who is familiar with the basic concepts can easily crack the logic of the program.Let's take an example:1) Write a program to print the pattern:1*2*3*4*17*18*19*20 5*6*7* 14*15*16 8*9*12*13 10*11Show Answer2) Write a program to remove all the vowels from a given string using switch case#include #include #include int vowel(char); int main() { char s[100], a[100]; int i, j = 0; scanf("%s" ,s); for(i = 0; s[i] != '\0'; i++) { if(vowel(s[i]) == 0) { a[j] = s[i]; j++; } } a[j] = '\0'; printf("%s\n", a); return 0; } int vowel(char ch) { switch(ch) { case 'a': case 'e': case 'i': case 'o': case 'u': case 'A': case 'E': case 'I': case 'O': case 'U': return 1; default: return 0; } } Note: You need to practice the programs as more as possible.Wipro Technical Interview Questions1) What are the functionalities of an operating system?These are some major functionalities of an operating system:The operating system shares the Computer's memory and sharing of the central processing unit time by various applications and peripheral devices.An operating system provides a user interface, i.e., graphical user interface and command line.An operating system includes functionality for booting the computer.Perform some basic tasks, i.e., managing the peripheral devices.It provides file management which refers to the way that operating system stores, retrieves, manipulates, and saves data.2) What is the difference between UNIQUE key and PRIMARY key constraints?Difference between unique key and primary key constraints:Unique keyPrimary keyA table can contain multiple unique keys.A table can contain only one primary key.NULL values are allowed.NULL values are not allowed.It helps to maintain a unique data in a column of a table.It helps to identify a unique row from a table.For MS SQL server databases, a unique constraint will generate a unique NON-CLUSTERED INDEXPrimary key will generate a unique CLUSTERED INDEX3) How can you delete the duplicate row in a table?In case of duplicate rows, you have to be more careful at the time of fetching records from the table.To overcome this problem, we use a DISTINCT keyword.It is used along with a SELECT statement to eliminate all duplicate records and fetching unique records.Syntax:The basic syntax to eliminate duplicate records from a table is:SELECT DISTINCT column1, column2,....columnNFROM table _nameWHERE [conditions]EXAMPLE:Let us take an example of the STUDENT table.ROLL_NONAMEPERCENTAGEADDRESS1AJEET MAURYA72.8ALLAHABAD2CHANDAN SHARMA63.5MATHURA3DIVYA AGRAWAL72.3VARANASI4RAJAT KUMAR72.3DELHI5RAVI TYAGI75.5HAPUR6SONU JAISWAL71.2GHAZIABADFirstly we should check the SELECT query and see how it returns the duplicate percentage records.SQL > SELECT PERCENTAGE FROM STUDENTSORDER BY PERCENTAGE;PERCENTAGE63.571.272.372.372.875.5Now let us use a SELECT query with DISTINCT keyword and see the result. This will eliminate the duplicate entry.SQL > SELECT DISTINCT PERCENTAGE FROM STUDENTSORDER BY PERCENTAGE;PERCENTAGE63.571.272.372.875.54) Define the SQL Profiler?SQL Profiler can be defined as the profiler utility which is mainly used to track connections to the SQL Server and also determine the activities such as which SQL Scripts are running, and which one is getting failed, etc.5) What is stored procedure? Explain with example.Stored procedures are a batch of SQL statements that can be executed in a couple of ways. Most of the DBMS support stored procedures; however, not all do. The stored procedure increases the reusability as here the code or the procedure is stored into the system and used again and again that makes the work easy.Syntax:CREATE PROCEDURE procedure_name AS sql_statement GO; To execute a stored procedureEXEC procedure_name; Create a table and use this syntax for example.6) What is a process and what is a thread?A thread is a lightweight sub-process, the smallest unit of processing. It is a separate path of execution.Threads are independent that means if there is an exception in one thread, it doesn't affect other threads. It uses a shared memory area.The process is heavyweight and can consists of multiple threads. It is a small part of a program.7) What are the advantages of a thread? How does the multithreading look like?These are the following advantages of a Thread:It provides efficient communication.It minimizes the context switching time.By using thread, we can get the concurrency within a process.Thread allows utilization of multiprocessor architectures to a greater scale and efficiency.A process which executes multiple threads simultaneously is known as multithreading.A thread is a lightweight sub-process, the smallest unit of processing.To achieve multitasking in java, we have two ways:Multiprocessing and multithreadingOne process may contain more than one thread and execute simultaneously is known as multi-threading.8) What are Multi-Processing and Multitasking?Multitasking: As the name indicates multiple tasks run on a single CPU. We use multitasking to utilize the CPU.Multitasking can be achieved in two ways:Process-based Multitasking (Multiprocessing)Thread-based Multitasking (Multithreading)Multi-processing: Multi-processing refers to the ability of a system to support more than one central processing unit at the same time.Multithreading: As the name indicates multiple threads run concurrently.A thread is a lightweight sub-process, the smallest unit of processing.9) What are stack and Queue and its applications?StackThe stack is an ordered list in which, insertion and deletion can be performed only at one end that is called a top.The stack is a recursive data structure having a pointer to its top element.Stacks are sometimes called as Last-In-First-Out (LIFO) lists, i.e., the element which is inserted first in the stack will be deleted last from the stack.Applications of Stack:RecursionExpression evaluations and conversionsParsingBrowsersEditorsTree TraversalsQueueA queue can be defined as an ordered list which enables insert operations to be performed at one end called REAR and delete operations to be performed at another end called FRONT.The queue is referred to be as the First-In-First-Out list.For example, people waiting in line for a rail ticket form a queue.Applications of Queue:The queues are widely used as waiting lists for a single shared resource like a printer, disk, CPU.The queues are used in the asynchronous transfer of data (where data is not being transferred at the same rate between two processes), e.g., Pipes, file IO, sockets.The queues are used as buffers in most of the applications like MP3 media player, CD player, etc.The queues are used to maintain the playlist in media players to add and remove the songs from the playlist.The queues are used in operating systems for handling interrupts.10) What is indexing, what are the advantages and disadvantages of it?Indexes are special lookup tables. It is used to retrieve data from the database very fast.An Index is used to speed up select queries and where clauses. But it shows down the data input with insert and update statements. Without affecting the data, we can create or drop indexesAn index in a database is just like an index in the back of a book.Indexing can be of the following typesPrimary index, secondary index, and clustering index.The advantages of indexes are as follows:An index makes it possible to retrieve data quickly.Index's use in queries usually results in much better performance.They can be used for sorting. A post-fetch-sort operation can be eliminated.Index guarantees uniquely identifiable records in the database.The disadvantages of indexes are as follows:Indexes decrease the performance on inserts, updates, and deletes.Indexes take up space (this increase with the number of fields used and the length of the fields).Databases will have monocase values in fields that are indexed.11) What is De-Normalization where does it have?Denormalization is the process of boosting up database performance and adding of redundant data which helps to get rid of complex data. Denormalization is a part of database optimization technique. This process is used to avoid the use of complex and costly joins.Denormalization doesn't refer to the thought of not to normalize instead of that denormalization takes place after normalization. In this process, firstly the redundancy of the data will be removed using normalization process than through denormalization process we will add redundant data as per the requirement so that we can easily avoid the costly joins.12) What are the Different Objects in DBMS?A database objects use to store or reference data in the database. Any statement which is written with CREATE Command is known as the database object.Different types of object in DBMS are:View: This object is used to create a view in the database. It is a logical table based on another view. A table on which view is based is called the base table.Table: we can create a table in a database by using the CREATE TABLE statement.Sequence: This object command used to create a sequence in the database. It is a user-created database object which is shared by multiple users to generate unique integers.Index: A database object can create indexes in the database by using an index. Indexes are used for fast retrieval of rows from a table.Synonym: This object is also used for creating indexes in the database. By synonym, you can easily access the objects13) What are Self-Join and Outer Join, where do you use it?Self-Join: A self-join is a join which joins the table with itself, means that each row of the table is combined with itself and with every other row of the table. The table contains a FOREIGN KEY which references its PRIMARY KEY.It shows the one-to-many relationship in a table also known as a unary relationship.Now come to SQL outer join, all the content of both tables is integrated together either they are matched or not.An outer join is of two types:1. Left outer join (also known as left join): this join returns all the rows from left table combine with the matching rows of the right table. If you get no matching in the right table, it returns NULL values.Syntax: Left outer joinSELECT table1.column1, table2.column2.....FROM table1LEFTJOIN table2ON table1.column_field = table2.column_field;2. Right outer join (also known as right join): this join returns all the rows from right table are combined with the matching rows of left table .If you get no column matching in the left table .it returns null value.Basic syntax for right joins:SELECT table1.column1, table2.column2.....FROM table1RIGHT JOIN table2ON table1.column_field = table2.column_field;14) Give a SQL Query which uses Outer Join.Syntax:Left outer joinSELECT table1.column1, table2.column2...FROM table1LEFT JOIN table2ON table1.column_field = table2.column_field;Let's take two tables in this example to elaborate all the things:CUSTOMER TABLE:IDNAMEAGESALARY1ARYAN51560002AROHI21250003VINEET24310004AJEET23320005RAVI2342000This is the second tableORDER TABLE:O_IDDATECUSTOMER_IDAMOUNT00120-01-20122300000212-02-20122200000322-03-20123400000411-04-201245000Join these two tables with LEFT JOIN:SQL SELECT ID, NAME, AMOUNT, DATEFROM CUSTOMERLEFT JOIN ORDERON CUSTOMER.ID = ORDER.CUSTOMER_ID;This will produce the following result:IDNAMEAMOUNTDATE1ARYANNULLNULL2AROHI300020-01-20122AROHI200012-02-20123VINEET400022-03-20124AJEET500011-04-20125RAVINULLNULL15) Explain some differences between TRUNCATE and DELETE commands with their syntax?There is a slight difference b/w delete and truncate statement. The DELETE statement only removes the rows from the table based on the condition defined by WHERE clause or remove all the rows from the table when the condition is not specified.But it does not free the space containing by the table.Syntax:DELETE FROM table_name [WHERE condition]; But if you do not specify the WHERE condition, it will remove all the rows from the table.DELETE FROM table_name; The TRUNCATE statement: It is used to delete all the rows from the table and free the containing space.Syntax:TRUNCATE TABLE employee; 16) Define memory management in C.When you run a program, it loads into your computer memory and starts execution by sending and receiving the instructions from the computer's processor. When your program needs to run a function, then it loads at another part of the memory till it runs and releases that memory when the task is complete.Now, talk about the concept of dynamic memory allocation in c language, which enables the C programmer to allocate memory at runtime. Dynamic memory allocation in c language is possible by four functions of stdlib.h header file.malloc()calloc()realloc()free()17) What are the steps involved in designing complete software?To build software, a programmer should have to follow the SDLC.Software development life cycle is a process of developing new softwareThere are six steps of SDLC:Planning: Plan about the scope, approach, functionalities, etc.Requirement analysis: Gather the required tools, data, and information that are required for the projectDesigning: Design a prototype to check the architecture of the project.Coding: coding as per designing.Testing: testing is done to check whether the actual result meets the required result.Maintenance: Updates18) What is the difference between Abstract classes and interface?Java interface should be implemented using the keyword "implements"; A Java abstract class should be extended using the keyword "extends."An Interface can extend interface only; Abstract class have two properties, it can extend only one java class but implement more than one interface at a time.19) What is the property of a class?We can define property in a way that property is a member of a class that provides the access of an object or a class to an attribute. For e.g., Properties include the length of a string, the size of a font, the caption of a window, the name of a customer, and so on.20) Define precondition and postcondition to a member function.A pre-condition is a condition that must be true before a method runs for it to workA post-condition is a condition that must be truly guaranteed after a method is finished.If all the preconditions of this method are satisfied, then postconditions will also meet for the same method.No guarantee for behavior if the preconditions not meet.21) How can you sort the elements of an array in ascending order?C program to sort the element of an array in ascending order.#include include void main() { int i, j, a, m, num[30]; printf("Enter the value of N \n"); scanf("%d", &m); printf("Enter the numbers \n"); for (i = 0; i 2 + 5 && 4) The given expression is equivalent to:((5 > (2 + 5)) && 4) The expression (2 + 5) will executes first and the result will be 7Then after first part of the expression (5 > 7) executes and gives 0 (false) as an outputFinally, (0 && 4) executes and gives 0 (false).Associativity:4 * 2 / 4 Here, operators * and / have the same precedence. Both "*" and "/" are left to right associative, i.e., the expression on the left is executed first and moves towards the right.Thus, the expression above is equivalent to:((4 * 2) / 4) i.e., (4 * 2) executes first and the result will be 8 (true) then, (8 / 4) executes and the final output will be 2 (true) 53) What is the rule for a catch or declare method declarations?Catch block catches any exception that results from the try block. If a checked exception is thrown within the body of the method, the thrown exception must be caught by the method (with the help of try/catch block) or declare it in its throws clause.54) What is the top class of the AWT Event Hierarchy?java.awt.AWTEVENT class is the highest-level class of AWT event hierarchy.55) When is a thread created and started, what is its initial state?A thread is created and started with its Initial state called "ready" state where a thread is ready to run.56) Is it possible to declare an anonymous class which implements an interface and extends a class?Yes, an anonymous class can extend its superclass or implement an interface but cannot use both simultaneously.57) Define Synchronization and why is it important?Synchronization is a process which provides a feature by which access of multiple threads to any shared resource can control.Hence, Java Synchronization is a better option for restriction. i.e., It allows only one thread to access the shared resource.The synchronization is mainly used toTo prevent thread interference.To prevent consistency problem.58) Is Sizeof a Keyword?Sizeof is an operator in C++ and a keyword in C, but it is not available in java.59) What is a priority of task and how is it used in scheduling?The entire task can't execute simultaneously so that a scheduler assign priorities to all tasks for its execution. Priorities can be high or low depending on the task's importance, and the integer values determine it.Higher priority gets CPU for execution first.60) Describe the three levels of data abstraction?Data abstraction in DBMS is a process of hiding irrelevant details from users. Because database systems are made of complex data structures, so it makes accessible the user interaction with the database.Following are three levels of data abstraction:Physical level: It is the lowest level of abstraction. It describes how data are stored.Logical level: It is the next higher level of abstraction. It describes what data are stored in the database and what the relationship among those data is.View level: It is the highest level of data abstraction. It describes only part of the entire database.61) What is Hashing technique in the data structure?Hashing is a faster searching technique. The process of mapping a large amount of data item to a smaller table with the help of a hashing function is called hashing. In other words, hashing is a technique to convert a range of key values into a range of indexes of an array.In terms of java: Hashing is a way to assign a unique code for any variable or object after applying any function or algorithm on its properties.Wipro HR Interview Questions1) Tell us about yourself.This is the most commonly asked questions for both freshers as well as experienced candidates.

I need respect and value that I deserve from him. He must care for the whole team members and encourage more creative work by honing the skills that I have."My ideal boss should be very energetic, positive attitude, positive thinking, polite, and knowledgeable about the work. He should have an ability to handle the critical situation, able to guide the employees in the right way so we can perform our best for better result for the company".My boss should focus on his duties, should remark on our work, fair with everyone and discuss the success or failure frankly".14) What is your weak point that you need to improve in your skills?This is also a common interview question in which the interviewer wants to check your confidence.You have to answer this question very carefully.For example:As a fresher, I have skills and knowledge that are relevant for entry level.You should set a high standard for yourself and try to meet them.I need to use my skills in real time industrial work so that I could learn new things and explore my skills and knowledge as more as possible.15) What do you know about Wipro? When did it come into existence?Wipro is an Indian information technology services corporation. Its philosophy is to think and implement, help clients to do business better.This company recognized globally for fast services, a strong commitment to sustainability and good corporate citizenship, we have over 160,000 dedicated employees serving clients across six continents.Founded: It was founded on 29 December 1945, it is the western India product company deals with vegetable oil, but later it has diversified into the manufacture of soaps and other consumer products. It ventured into technology in 1985, selling locally-made computersHeadquarter: BangaloreRevenue: 840 crores USD (2018)Founders: M.H Hasham Premji, Mohamed PremjiChairman: Azim H. PremjiCEO: Abidali Neemuchwala16) What is your salary expectation?It is very frequently asked interview question. According to your performance, some companies give you a chance to negotiate about salary and some companies having a fixed salary for entry level.So you have to answer this question as "As per company norms."Still, if the interviewer asks for your expectation, then you have to answer according to your expectation.Remember that you are fresher so tell your expectation accordingly.17) I have done from my side; do you have any question for me?Well, this would be the last question which has been asked by the interviewer whether it has a technical interview or HR interview.You have to answer this question "Yes," and ask an intelligent question which influences the interviewer to let you go at least for the next round.For example: What would be the next round?Is there any bond that we have to sign? Etc.18) If anybody doesn't cooperate with your team what are the steps you would take.This is a big problem for the organization. When you are dealing with problematic employees in your team then the work productivity goes downward, frustration rise, the customer gets upset.You have to follow these steps to handle these types of team members.Don't ignore this problem: Generally, the manager will ignore the problematic staff. Ignoring the situation is not a solution. So you try to avoid ignorance.Intervene as soon as possible: This problem affects the production, hence should have to take action as soon as possible. The manager needs to gather information from an employee that what is the reason behind it, and personally analyze the issue.Reach the problem personally: Manager needs to take the employee into a conference room or office (away from the others) and try to locate the problem.The manager tries to know whether the employee is aware of this issue if he/she has not aware of this issue than it is a responsibility of the manager to let him know about the problem.Help the problematic employees to get back on track:Once the manager let him aware of the problem, and the employee begins to understand that this negative behaviour is real, and experienced by others which are not right for the organization. Then the employee tries to get back on track and think for the organization.If all possible ways get fail, then termination may be necessary.If the employee continuously shows inadequate behaviour and don't try to cooperate. In this case, termination is required.19) Are you willing to relocate?We all know that Wipro is a huge, rapidly growing company which provides service to clients in 175+ cities. So definitely no one wants to leave this company easily.You have to answer in two ways: You can say that yes I am definitely willing to relocation. This shows that you will follow the necessary terms which are good for the company and your team.If you are not wanted to relocate, then you don't have to say that you are not willing to relocate. Instead of saying "no," you have to use the sentence, "I would like to continue in this city because my family is here, but this position is a great opportunity for me. I couldn't leave this opportunity. If relocation is required, then I would definitely consider it".20) Are you comfortable with working over weekends?As we all know that Wipro is listed in top MNC's, so as per my decision, I would say "yes," whenever the organization needs me, I will definitely be there either in night shift or weekends. As per my observation, the company's growth is directly proportional to employee's growth.You have to cooperate with the company than you will get a good result definitely.

Java is Platform independent because when we write code, then its compiler converts it into bytecode and this bytecode can be executed on any platform (JDK should be installed in that OS).2) What do you understand by Exception Handling?Exception handling is a process of handling exceptions occurs during the execution of a program. Due to the occurrence of exception, execution of programs get halted, so it is very important to handle these exceptions so that program can be executed smoothly. We can handle the exceptions by using five keywords: try, catch, throw, throws, and finally.3) What is checked and unchecked exception?Checked exception: If the exception occurs or checked at compile time during the execution of a program, it is called as the checked exception. We should handle these exceptions using try-catch block or using throws keyword.E.g., if someone tries to read a file which is not present then it will throw a checked exception at compile time FileNotFoundExceptionUnchecked exceptions: If the exception is not checked at compile time and occurred at runtime then this type of exception is called an unchecked exception. This type of exceptions occur due to an error in the logic of the code. If we do not handle this type of exception then also compiler will not give a compilation error.E.g. ArithmeticException4) What are the reasons behind the occurrence of an exception?Following are the reasons behind the occurrence of an exception:Accessing a file, which does not existDividing a variable by zeroInserting an element in the array outside the rangeIf throw statement occursAbnormal execution condition captured by JVM5) What is OOP concept?OOP stands for Object-Oriented Programming. Object-Oriented Programming is a coding practice which works with objects and class. Java is one of the programming languages which is based on these concepts. The basic OOP concepts are:ObjectClassInheritancePolymorphismAbstractionEncapsulation6) Explain the basic features of OOPs.Following are the basic features of OOPs:Object: - An object is a physical entity which has a state and behaviour. It occupies space in memory. It is a sample of a class. Object helps to access the methods and variables in the program.Class - A Class is "collection of objects." A class is a logical entity, which does not take any space. A class includes all the data and methods which shows the behaviour of an object.Inheritance - Inheritance is a process by which one class can have all properties of other class. Inheritance increases the code reusability. There are two terms usedChild class (Subclass): Class which inherits other class, called as Child class or derived class.Parent class (Superclass): A class which got inherited by another class is termed as parent class or Base class.Polymorphism: - Polymorphism is a method of performing "a single task in different ways." Polymorphism enables a programmer to use methods or operators in different ways. In Java, we use method overloading and overriding to obtain the polymorphism.Abstraction: If we show only functionality and hide the explanations or details then this process is called as Abstraction. For achieving the abstraction, we use two ways in JavaAbstract classInterfaceEncapsulation: Encapsulation is a process of enclosing the data and code together to form a single unit. It makes the data safer within the code for any modification. For achieving the encapsulation, we can declare the data variables of class as private.7) Differentiate between class and object.The class and object both are the features of OOPs concepts. The basic differences between both features are given below:The Class is a logical entity whereas Object is a physical quantity.Class does not occupy memory at the time of creation whereas Object occupied space in memory when it is created.For declaring a class, we use a 'class' keyword followed by a class name, whereas we can create the object using the 'new' keyword in Java.A Class is like a factory which generates object and object are the instances of the class.8) What is encapsulation in Java?Encapsulation is a process of enclosing the data and code together to form a single unit. The best example to understand the encapsulation is a capsule which contains the medicine in it.If we declare all the data members of the class as private, then it is called a fully encapsulated class in Java, and then we can use getter and setter method to access it.One of the examples of the fully encapsulated class is Java Bean class.Encapsulation keeps its data hide from other class hence it is also called as data-hiding.Example for encapsulation:class EncapsulationEg{ private String empname; private int empage; private int empid; public String getEmpName() //getter method { return empname; } public int getEmpAge() { return empage; } public int getEmpId() { return empid; } public void setEmpName(String setvalue) //setter methods { empname=setvalue; } public void setEmpAge(int setvalue){ empage=setvalue; } public void setEmpId(int setvalue){ empid=setvalue; } } public class TestEncapsulation{ public static void main(String args[]){ EncapsulationEg en= new EncapsulationEg(); en.setEmpName("Alvin"); en.setEmpAge(22); en.setEmpId(12568); System.out.println("Employee Name: " +en.getEmpAge()); System.out.println("Employee Age: " +en.getEmpAge()); System.out.println("Employee ID: " +en.getEmpId()); } } Output:Employee Name: 22 Employee Age: 22 Employee ID: 12568 9) What is Recursion and recursive function in Java?Recursion is a process of calling a method by itself continuously till not get termination point. A method which calls itself is called as a recursive method.Syntax:Return-type method_name() { // Code to be executed method_name(); // same name of calling method } 10) How can you differentiate between C, C++, and Java?There are the following differences between the C, C++, and Java language.IndexC languageC++Java1.C language is a procedural language.C++ is an object-oriented language.Java is also an object-oriented language (not pure as it also supports primitive data types).1.C language is platform dependent.C++ is platform dependent.Java is platform independent language.1.C language supports pointers.C++ language also supports pointers.Java does not support pointers.1.We cannot create our own package in C languageIn C++ language also, we cannot create our package.In the Java language, we can create our package and can specify the classes.1.In C, there is no any concept of inheritance.In C++, we can use multiple inheritance.Java does not support multiple inheritance.11) What do you understand by runtime polymorphism?Polymorphism is a method of performing "a single task in different ways." Polymorphism is of two typesRuntime PolymorphismCompile-time polymorphismHere we will discuss runtime polymorphism.Runtime Polymorphism- We can achieve runtime Polymorphism by method overriding in Java. And method overriding is a process of overriding a method in the subclass which is having the same signature as that of in superclass.class A{ //Superclass void name() { System.out.println("this is student of Superclass"); } } class Student extends A //Subclass { void name(){ // method Override with same signature(runtime polymorphism) System.out.println("this is student of subclass"); } public static void main (String[] args) { A a= new A(); // refrence of A class A b= new Student(); // refrence of student class a.name(); b.name(); } } Output:this is student of Superclass this is student of subclass 12) How can you differentiate between method overloading and method overriding?No.Method overloadingMethod overriding1.The process of calling two methods having the same name with different parameters is called method overloading (in the same class)The process of calling two methods, one in the subclass and other in the superclass, having the same signature is called as method overriding.2.It can be accessed within a class.Method overriding requires two classes to be accessed which having IS-A relationship.3.Return type may be changed or may remain same with different parametersReturn type should be the same for both methods.4.Method overloading is a concept of compile-time polymorphism.Method overriding is a concept of method overriding.5.e.g. class A{void m1(){// codes.......}Void m1 (int a) {//code.........}e.g. class A {void m1(){// code............}}Class B extends A{Void m1(){// code...........}13) What are the keyword "super" and "this" in Java?super keyword: "super" is a keyword in Java which is used to give reference to the object of parent class. "super" keyword cannot be used as an identifier as it is reserved keyword in Java.this Keyword: "this" keyword in Java is used to refer to the object of the current class. The 'this' keyword cannot be used as an identifier as it is a reserved keyword in Java.14) What is an interface in Java? Can we implement multiple interfaces in one class?Interface in Java is a way to achieve the abstraction. The Interface is like a class but not exactly as Interface also can have methods and variable as the class does but Interface only contain method signature does not have the body.The Interface cannot be instantiated in Java.The Interface contains methods which are public and abstract (by default).A class can implement an interface.For declaring an interface, we use the keyword interface.Syntax:interface Interface_Name{ //Methods } We can implement multiple interfaces in one class and parent interfaces can be declared using a comma(,) operator.Syntax:public class A implements C, D { Code } 15) Explain inheritance in Java? How can it be achieved?Inheritance in Java is a process by which one class can have all properties of other class. That means one class inherits all the behaviour of the other class.Inheritance increases the code reusability.Inheritance is an important feature of OOP concept.Inheritance is also a representation of the IS-A relationshipThere are two terms used in inheritance:Child class (Subclass): Class which inherits other class, called a Child class or derived class.Parent class (Superclass): A class which got inherited by another class is termed as parent class or Base class.The Syntax of java inheritance:Class A extends B // Here A represents subclass and B represent Superclass { // Code } 16) Can we use multiple inheritance in Java? Explain with reason?No, we cannot use multiple inheritance in java as it creates ambiguity and diamond problem in the program. To overcome this problem, we can use interface in Java.Let suppose class A inherits the two parent class B and C in which a method with the same name is present in both the classes and hence when we try to override that method it will create confusion for the compiler and will give the compilation error. Therefore, Java doesn?t support multiple inheritance.17) What can we do if we want to access a private member of a class?We can access private members of the class by using public getters and setters from outside the class in Java.18) What is the significance of "static" keyword?Static keyword in Java is a non-access modifier which can be used with the block, variable, methods, and nested classes.Static Keywords are the part of the class, and it does not belong to the instance of the class.We use static keyword in java with variables, block, and method for achieving memory management.Java static property can be shared by all the objects.For accessing the static members, we don't need to create the instance of the class.19) What is "Collection Framework" in Java?Collection Framework in Java is an architecture for storing the classes, and interfaces and manipulating the data in the form of objects. There are two main interfaces in Collection Framework that are:Java.util.CollectionJava.util.Map20) What is List interface in collections?List interface is an interface in Java Collection Framework. List interface extends the Collection interface.It is an ordered collection of objects.It contains duplicate elements.It also allows random access of elements.Syntax:public interface List extends Collection 21) What do you understand by object cloning?Object cloning is a mechanism of creating the same copy of an object. For object cloning, we can use clone() method of the Object class. The class must implement the java.lang.Clonable interface, whose clone we want to create otherwise it will throw an exception.Syntax of clone() method:protected Object clone() throws CloneNotSupportedException 22) Can we insert duplicate values in Set?We cannot insert duplicate elements in Set. If we add a duplicate element, then the output will only show the unique elements.23) What is the difference between Collections, and Collection in Java?Collection and collections both are the part of Java Collection Framework, but the primary differences between both are given below:A Collection is an interface in java and Collections is a class of collection framework.The Collection interface provides the methods that can be used for data structure whereas Collections class provides the static methods which can be used for various operation on a collection.24) What is "Diamond problem" in Java? How can it be removed?The Diamond problem occurs in multiple inheritance, but Java does not allow multiple inheritance. In case of Java, it can occur with interfaces. When we implement two interfaces which are having methods with the same signature then it creates ambiguity for the compiler, and it gives compile time error. Its structure looks like diamond so it is called as Diamond problem.E.g. Let's take an example which will show the diamond problem.interface InterfaceA { default public void m1() { System.out.println("This is interface A!"); } } interface InterfaceB { default public void m1(){ System.out.println("This is interface B!"); } //same signature as interface InterfaceA? } public class Simple implements InterfaceA, InterfaceB { public static void main(String args[]) { Simple s1= new Simple(); s1.m1(); // It will give error.. }} Error: Simple.java:10: error: class Simple inherits unrelated defaults for m1() from types InterfaceA and InterfaceB25) What is an abstract class in Java?An Abstract class is used to achieve abstraction in Java. If we use the keyword "abstract" with the class name, then it is called as an abstract class.An Abstract class can have only methods without body or can have methods with some implementation.The Abstract class cannot be instantiatedIt's not necessary that an abstract class should have an abstract method.Syntax:abstract class Student{ } 26) What is deadlock condition in multithreading?A Deadlock condition occurs in the case of multithreading. It is a condition when one thread is waiting for an object lock, which is already acquired by another thread and the second thread is waiting for lock object which is taken by the first thread, so this is called deadlock condition in Java.27) Differentiate between Collection and array.The Collection and Array both are responsible for storing the data, but the fundamental differences between both are given below:Arrays are always of fixed size, we cannot change its size at runtime, but In Collection, size can be changed dynamically.Arrays can only store homogeneous or similar type objects, but in Collection, both homogeneous and heterogeneous objects can be stored.Arrays cannot provide the "ready-made" methods for user requirements as sorting, searching, etc. but Collection includes readymade methods to use.Arrays are good in performance as compare to Collection but Array take more space in memory in comparison to Collection.C/C++ Interview Questions28) What is call by value and call by reference?There are two ways in C language to pass the values in the function that are:Call by ValueCall by referenceCall by value: In call by value, a copy of the value is passed to the function so, if we change in formal parameters it will not affect the actual parameters. When we change in the value of the formal parameter in the "calling function," it just takes it as the local variable and does not affect the actual value.Call by reference: In call by reference, an address of that value is passed to the function so, if we make any changes in formal parameters it will affect the actual parameter as well.29) Explain dynamic memory and static memory allocation.There are two types of allocation of memory:Static memory allocation: The allocation of memory at the starting of the program is called static memory allocation. In static memory allocation size remains fix i.e. we cannot change the size at runtime. Static memory allocation is used in Array.Dynamic memory allocation: The allocation of memory at runtime is called as dynamic memory allocation. We can specify a size at runtime as per need. The memory gets allocated from heap area, and it can also be deallocated from same. Dynamic memory allocation used in pointers.30) What is difference between "var++" and "++var"?The expressions, ( var++)and ( ++var) both are used for the incrementing the value of variable var.The main difference between both is that, (var++ ) it gives the evaluation of statement first and then it increments the value by one whereas (++var) is used as it increments the value by one before the evaluation of the expression.E.g.#include int main() { int a,b; a=5, b=1; printf("%d %d", a++, a); //will generate 5, 6 as output printf("%d %d", ++b, b); //will generate 2, 2 as output ) 31) Differentiate between class and structure in C++.The class and structure both are approximately equivalent to each other. But the main differences between both the terms are given below.The members of the class are accessed as private by default whereas members of the structure are accessed public by default.Class in C++ is a group of objects, related variables, and functions, whereas Structure is a user-defined data type which performs its operationWe can declare a class using the keyword 'class', whereas we can declare a structure using the keyword 'struct.'The objects of the class, created at heap area of the memory, whereas the object of the structure created on stack area of memory.32) What are the access specifiers in C++?We use access specifier to prevent the access of the class members or to implement the feature of Data Hiding. In C++, there are some keywords used to access specifier within class body, which are given below:Public: If we specify a class member as public then it will be accessible from anywhere within a program. We can directly access the private member of one class from another class.Private: If we specify any class member as private then it will only be accessed by the function of that class only. We cannot access the private member of the class outside the class.Protected: Protected access specifier is mainly used in case of inheritance. If we define the class member as protected, then we cannot access class member outside the class, but we can access it by subclass or derived class of that class.E.g. Below is the example to show the access specifier in C++.33) Why we use of "getch()" in a program?The getch() function is a predefined library function which is used to take a input character from the screen, and it holds the screen till it not get character from input.#include main() { printf("enter the character. \n"); getch(); } Output:enter the character. 34) What does "main()" function in C++? Can we run a program without main method?In C++ programming language the main() function is the entry point of that program. When we start execution of any program, execution directly goes to the main() in the program.Syntax for main():void main(){ ///Program body; } 35) What is the declaration and definition of a variable?Declaration of Variable: Declaring a variable or function is that we are declaring the name and its type so that it can be used in the program. The Compiler can understand and use those variables and functions. Declaring a member gives its representation in that program.e.g.extern int x; extern char y; // It tells the compiler that there are two variables x and y of types char and int Definition of Variable: Defining a variable means, we are providing some value to it, or we are initializing it with some value. Defining a variable or any member of the program gives the complete information about it.e.g.int x= 2; char y = 'A', 'B'; // It defines the variable x and y by giving its value or body. 36) What do you understand by Friend function?A friend() function in C++ is a function which can access private and protected members of another class in which it is declared as a friend. We can declare a function as a friend function by using keyword friend. A friend function can be of two types:Method of another classA global functionSyntax:class Class_Name { //Line of code friend return-type func_name() ;} The above-declared friend function can use private members of the class.37) What is memory allocation in C?Memory allocation is a process of allocating or reserving some portion of the memory (or as per need) for the execution of the code.There are mainly two types of memory allocation in C:Static memory allocationDynamic memory allocationStatic memory allocation: The allocation of memory at the starting of the program is called static memory allocation. In static memory allocation size remains fix, i.e., we cannot change the size at runtime. Static memory allocation is used in Array.Dynamic memory allocation: The allocation of memory at runtime is called as dynamic memory allocation. We can specify a size at runtime as per need. The memory gets allocated from heap area, and it can also be deallocated from same. Dynamic memory allocation used in pointers. There are four types of the predefined function used for dynamic memory allocationmalloc()calloc()free()realloc()38) Differentiate between malloc() and calloc()?The malloc() and calloc() are the two pre-defined library function available in Library. Both the functions are used for dynamic memory allocation for the execution of the program. The basic differences between the malloc() and calloc() are given below:The malloc() stands for memory allocation while calloc() stands for contiguous allocationThe malloc() allocates a single block of memory whereas calloc() allocates multiple blocks of memory.The malloc() takes only one argument, i.e., size of given block. Whereas calloc() takes two arguments, i.e., a number of blocks to be allocated and size of all blocks.The malloc() function is faster than calloc() function for memory allocation.Syntax for malloc() function:ptr= (type_cast*) malloc( size_t size ); Syntax for calloc() function:ptr= (type_cast *) calloc(n , size_t size ); 39) Why is C a procedural language?Procedural language defines a language which follows some pattern, hence C language is called as procedural language as in C language a programmer must follow a specific pattern or flow of the program. C language follows a top-down approach to solve a problem. It mainly focuses on the flow of the program rather than the data.DBMS interview questions1) What do you mean by data structure?A data structure is a specific way of arranging and managing the data in the computer so that it can be accessed efficiently and can be modified and updated easily. Some examples of data-structure are given belowArrayLinked ListQueueStack, and many more.2) What is normalization? What are its types?Normalization is the process of organizing the data in the database to reduce redundancy of the data and achieving data integrity. It is also called as database normalization or data normalization.By normalizing the data we can arrange the data in tables and columns, and a relationship can be defined between these tables or columns.There are following types of normalization available which are used commonly:First normal form (1NF)Second normal form (2NF)Third normal form( 3NF)Boyce & Codd normal form (BCNF)Fourth normal form(4NF)3) Explain the "primary key," "foreign key," and "UNIQUE key" in Database?Primary Key: A primary key in the database, is a field or columns, which uniquely identifies each row in the database table. Primary key should have a unique value for each row of the database table. And it cannot contain null values. By default, a primary key is a clustered index.Unique Key: A unique key also works as primary key except that it can have one null value. It would not allow the duplicate values. By default, the unique key is the non-clustered index.Foreign Key: A foreign key is used to create a link between two tables. It can be defined in the second table, but it will refer to the primary key or unique key of the first table. A Foreign key can contain multiple null values. A foreign key can be more than one, in the table.4) What is XML in DBMS? Explain its types?XML in database termed as "eXtensible Markup Language."XML database is designed for storing and transporting of the significant amount of data in the XML format.XML database is primarily associated with document-based databases.There are two types of XML database used which are:XML-enabledNative XMLXML-enabled Database: - XML-enabled Database is same as RDBMS where data can be stored in tables which consists of columns and rows. It is an extension for the conversion of XML documents.Native XML database: - Native XML-database stored the data which is based on container not in the format of a table. Using the Native XML database we can save the considerable amount of data. We can query the data in Native-XML database using X-path expressions.5) Differentiate between CHAR and VARCHAR2?We use CHAR and VARCHAR2 in the database to store the string in the database. But the main difference between both the terms are given below:CHAR is of fixed size, and VARCHAR depends on the size of the actual string which we want to store.If we use CHAR to store a string, then it will take memory as the size we have defined, but VARCHAR2 will take the memory as per the size of the string. So using VARCHAR, we can use memory efficiently.6) Differentiate between DELETE and TRUNCATE command in SQL?We can use two commands to delete a row from the Table that are TABLE and TRUNCATE command.The main differences between both the commands are given below:TRUNCATE is a known as DDL command whereas DELETE is a known as one of the DML commands.DELETE can remove some rows from the table and TRUNCATE command can be used for removal of all rows from the Table.IF we use DELETE command without using WHERE clause it will delete the complete table, but it will not free the container space whereas TRUNCATE command will remove the entire TABLE and free the space which table contains and we cannot use WHERE clause with it.DELETE command does not reset the identity of the table whereas TRUNCATE can reset the identity of the table.The Syntax for DELETE command:DELETE FROM table_name [WHERE condition]; // WHERE clause is optional to use. It will delete the selected rows which match the WHERE clause conditionsThe Syntax for TRUNCATE command:TRUNCATE TABLE table_name; It will delete the complete table and free-up space7) What is DML command in DBMS?DML stands for Data Manipulation Language. The SQL commands which deals with data manipulation are referred to DML. Some DML commands are:SELECT- This command is used for retrieval of the data from the table of given database.INSERT- This command is used to insert or add the data into the table.UPDATE- This command is used to update the existing data in the table.DELETE- This command can be used to remove the records from the table.8) Why do we use DBMS?DBMS stands for "DataBase Management System". It is used to deal with Data.Following are the uses of DBMS:Creation of the DatabaseManaging the data in the databaseUpdating of data in the databaseFor the retrieval of data from the database.Efficient memory managementDBMS provides the Security of the data9) Differentiate between "Hot Backup" and "Cold Backup" in the database?In the database we can take backup of data in two ways:Cold backupHot backupCold Backup: - Cold backup is a physical backup, and it is also termed as the offline backup. Cold backup, works when the database is in offline mode, and no any user is logged-in. In the cold backup, all the files are copied without risk of any change. It is a more secure way of backup of data and control files. E.g., A USB drive or hard drive can also be considered as the cold backup, if it is unplugged after each backup.Hot Backup: - Hot Backup is also a physical backup, and it is termed as Online-backup. Hot backup is a backup which performed on data while the database is active for all user. Hot backup has a risk as it is available and open for all users. It is used if we want the complete backup of the database. Oracle provides a preferred method of backup, i.e., Recovery Manager (RMAN).10) What are ON DELETE CASCADE options in DB table?MySQL provides an effective way to delete the data from the database table is called as ON DELETE CASCADE option. It works in reference to the foreign key, in which if we remove the data from the parent table then data will automatically be deleted from the child table.11) What is the AVL tree? What is its significance?AVL tree is named after its invention by Adelson-Velsky and Landis. AVL tree is a height-balanced binary search tree of the self-balanced binary search tree in which:Each node of the AVL tree is associated with a balancing factorBalancing factor can be calculated as the difference between the heights of the left and right sub-tree cannot be more than one for each node in the tree.Balance Factor (k) = height (left (k)) - height (right (k)) Time complexity: Since AVL tree is balanced, its height is O(log (n)) and hence time complexity for insertion is O(log n).The Significance of AVL tree: As binary search offer good performance while searching in balanced case, but if they are unbalanced their searching performance can be reduced hence to overcome this problem we can use AVL tree as it is a self-balanced binary search tree. Therefore, it ensures a time complexity of O(log(n)).12) Explain the turnaround time and response time? (OS)Turnaround time: - Turnaround time defines the amount of required time to complete a request.Response time: - Response time is the average time which is required for submission of the request, and the first response occurred.Accenture Third Round: HR interview QuestionsHR round is the last round of the Accenture recruitment process. In this round, Interviewer checks the communication and professional skills of the candidate.A list of the top most asked HR question with examples:1) Brief about yourself in a minute?If we say "The first impression is the last impression" then it will the perfect fit for this question. In the most of the cases during an HR interview, it would be the first question, and you have a very first chance to impress the interviewer with your perfect and enthusiastic answer.a.) The aim of the question:Before answering this question, you must know why this is the very first question and why it is asked? So by asking this question interview starts the conversation and he just wanted to examine whether the candidate is suitable for the job and job environment, by knowing in detail about the candidate.b.) How to Answer for this question:Now, how you can fulfil the expectations for this question. So the first thing that before answering this question you must be full of confidence and relaxed and then start answering.Following is the flow for the answer to this question:Introduce Yourself: The very first sentence must be your basic introduction to yourself in a very professional way. The Interviewer just want to know about yourself so concentrate and be precise.About your academics and previous experience (if have): After introducing yourself, the next thing come is to give the brief knowledge to the interviewer about your academics and your previous experience so that the interviewer can judge whether you fit into basic job criteria or not. So give only overview about your recent academics and experience, not the whole story.Family background (Optional): Tell about your family background is totally optional. If the interviewer gave you enough time for introduction then you can tell it else it's not mandatory.Hobbies, strength, and goals: This is the step where you got another chance to impress the interviewer. But the most important point for this step is to be real or truthful that means you should not boast yourself.Conclude: Now, conclude the answer with the smile and prepare to answer to the next question.Example introduction:Hello/Good morning/ after noon, my name is XYZ, and I belong to the city New Delhi. Before starting to introduce myself, I would like to thank you for this great opportunity. I did my schooling from St. Mary?s Convent School and scored 75% in higher secondary and scored 80% in senior secondary. I have completed my B. Tech from Amity University and scored 75% marks. I got trained and certified for multiple technologies as core and advanced Java, HTML, SQL. I worked on a project which was based on the web-based application for digital marketing. My hobbies are playing cricket, and I love singing and creating various types of application tools. My strengths are that I am very adaptive, and having leading qualities. My Objective is to join this organization where I can prove myself by doing my level best so that it can polish my skills as well as I can give minor support with full efforts to grow this organization.2) Why did you apply for this job?This is the next crucial question which can enhance your chances to be selected. So in this question, the interviewer just want to know whether you know about the company and about your role in that company. The first thing you should remember that you must have good knowledge of the company and as well as the role for which you have applied.How to answer:To answer this question, you must try to match your skills to the job description. The interviewer wants to hire those candidates who have the sufficient knowledge about the role for which they have come. Try to give some good points of the company in front of the interviewer and try to show interest in yourself with that points of the company.Example:I have applied for this Job as I feel it will be best suited to me as per skills. I can give my best for this job. When I was going through job-description I have noticed that you have mentioned that you need someone who can do____________, so I was very excited as I have very good knowledge in this field as I have also worked on the project at my college time and even got trained in this technology. 3) How have you prepared for this interview?While preparing for an interview, no one thinks that the interviewer can ask about the preparation strategies and then we got stuck with this question. But there are also some tips to tackle such type of questions.By asking this question, the interviewer wants to check that how sincere and how serious you are for this job opportunity so answer in this way only.How to Answer:There are some points below mentioned which you need to keep in mind while answering this question:Try to ensure the interview that you have searched about the company profile as well as product and service of the companyAnswer in a way that you were really interested in this interview and hence also studied and prepared for technical and aptitude rounds.Tell about good points, people reviews for the company and if any improvement can be possible (in a positive way)Example:When I got to know about this interview, firstly I got excited about this as I was eagerly waiting for such an opportunity. But I was not much aware of the company?s service and products hence I searched a lot for it and also many interesting points for this company (brief some point). Then I went through the Job description and requirement and refreshed my theory and practical part of technologies. So this way, I have prepared myself for this interview.4) What is your biggest achievement till now?This question is a fascinating question of an interview as the interviewer wants to know about yourself in deep. By this question the interviewer wants to know that:What makes you creative in your life?Which things drive you?What really matters for you in your life and what motivates you?What is your potential?How to Answer:This question should be answered in a way that picks up the interviewer interest. So, there are some ways to answer this question:Keep your answer real that means just tell those achievement which you proud of.Keep it recent that means to tell that biggest achievement which you have in recent years.Keep it professional. Your answer should be professional for your achievement.Example:I have got various achievements in my carrier, but the most notable achievement was the delivery of my college project. We have opt to create an iOS mobile app, as some of our team members including me was having reasonable knowledge of iOS, and the guy who was leading us was senior and had worked with many iOS projects. But due to some issue, he needs to go out of town so, I was selected as lead for that project. So with my continuous practice and enthusiasm including my team members, we have completed our task, and our project was one of the best projects of our college.5) What do you know about our Company?This is a very likely question for most of the interviewer, in this question the interviewer wants to check two things in the candidate:Do candidate really care about the company and his role that means they want a candidate who is sincere enough about the company and don't want any candidate who comes in the interview without knowing the details about the company.Whether the candidate is a good researcher or not.

This interview round includes the question on the basis of different technologies such as C/ C++, JAVA etc. There will be no specific time limit and it totally depends on candidate knowledge. There is a list of some most asked technical interview questions in IGATE recruitment process, given with the most suitable answer.1) Differentiate between low-level language and high-level language?A computer cannot understand the human language, so we need a different type of language to communicate with the computer. There are various types of languages which a computer can understand and work accordingly so, there are two types of languages:Low-level language and high-level language.The main differences between both the languages are given below:Low-level languageHigh-level languageLow-level languages are machine dependent languages that means we cannot execute it on other platform.High-level languages are machine independent languages that mean we can execute it any platform (Mac, Windows, and Linux).Low-level languages are more machine-readable.High-level languages are more human-readable.It is difficult to write and compile a low-level language.It is easy to write and compile a high-level language as compared to low-level languageIt is difficult to find errors and debug a program in a low-level language.Finding an error and debugging is easy in a high-level language.Low-level languages are written in binary form, so these are faster than other languages.High-level languages are written in some human readable instruction which needs to convert to binary form so these are slower thanExample of low-level language is machine language.low-level languagesExample of high-level language is C++, Java etc.2) Explain an interface in Java language?Interface in Java is a way to achieve the abstraction. An Interface is like a class and also can have methods and variable as a class does but Interface only contains method signature and does not have a body.An Interface cannot be instantiated in JavaAn Interface includes methods which are public and abstract (by default).A class can implement an interface.For declaring an interface, we use the keyword interface.Syntax:Interface Interface_Name{ //Methods } 3) How can we create an interface in Java?To create an interface in Java, we can use the keyword "interface" followed by the interface name.Exampleinterface Employee { int empid = 23; String empname="John"; } We can implement an interface in a class by using keyword "implement" and can use abstract methods.4) What is immutable class and how to create an immutable class in Java?An immutable class is one in which once an object is created, then we cannot alter the values, or we cannot change its content. As in Java, we have wrapper classes like String, Boolean, Integer, etc., all these classes are immutable classes, and we can also create an immutable class by own.Following are some requirement to create an immutable class in Java:A class needs to declare as final so that it cannot be inherited.All the data members of the class need to declare as final so its value can't be changed.No option for setters method.There should be getter methods for all variables.5) "String class is immutable", explain the reason?String class is immutable in Java that means we are unable to change its value. It is because a String object is always cached in the String pool, and these pools can be shared between various clients. So there will always a risk that if we change in client's string it will automatically affect all the client's action. So every time when we try to change the String value, it will create a new object6) How can we inherit the constructor in a class, in Java?We cannot inherit the constructor in the class. If we try to inherit a parent class constructor to the child class, then it will give the compile-time error because Constructor name should be same as the class name and constructor inheritance is against the constraint of Constructor.Example:class ConstructInheritance{ ConstructInheritance() { System.out.println("This is Parent class Constructor"); } } class Child extends ConstructInheritance{ Child() { System.out.println("This is Child class Constructor"); } public static void main (String[] args) { Child obj= new Child(); Child obj2=new ConstructInheritance(); } } Output:Error message: prog.java:10: error: invalid method declaration; return type required ConstructInheritance(){ Note: Although we can call parent class constructor in child class using super() method in a child class7) What is a static keyword in Java? What is its significance?Static keyword in Java can be used primarily for memory organization. A static member in Java class always belongs to its class, not an instance. A static keyword can be used with:BlocksVariablesMethodsNested classTo create a static member, we need to declare it as static. The instance of a static member created only once, and it is shared across all the objects. A static member can be accessed before its object is created.class Employee { static int i; //static variable static void m1() //Static method { System.out.println("This is static mehtod "); } static //static block { for(i=1; iMinimum redundancy of dataLogical data integrity.Normalization increases the performance of the database, as it allows a database to take very less space in memory.There are mainly four types of Normalization, which are given below:1NF: A relation in the table be in first normal form if each attribute is single value attribute2NF:3NFBCNF10) Can we check whether a link list is circular or not?Yes, we can check that a given link-list is circular or not. A link-list will be a circular link-list if it follows the two main requirements:If a link list is not null terminated( it points to the first node)If all nodes are connected in the form of cycle.11) What does itoa() function in C?The itoa() function in C language used to convert an integer value to its equivalent null-terminated String. It stores the result in an array.Syntax:char * itoa ( int value, char * str, int base ); Parameters:value: A value which needs to be convertedstr: A parameter which stores the converted value as an arraybase: It represents the numerical value, which is used to give the conversion base, as base 2 for binary, base 10 for decimal.12) How can determine the size of the class?The size of a class depends on the size of its members. There are the following factors which determine the size of a class:Size of all non-static members of the classSize of its immediate parent class(if have)13) What do you understand by aggregation? How it differs with the association?In UML (Unified Modeling Language) there are various types of relationships for the object-oriented system. Association and Aggregation are also a type of relationship in UML.Aggregation: Aggregation is a specific type of association between two or more objects. In Aggregation, objects can have their lifecycle with ownership. It is a one-directional association. If we destroy one object, it will not affect another one. It is also called as HAS-A relationship.Association: Association is a relation between two objects with their own lifetime and without any ownership. An association relationship can be represented by the following type:One-to-oneOne-to-manyMany-to-manyThe aggregation and composition are the part of the association.14) Differentiate between constructor and destructor?(C++)Differences between constructor and destructor are given below:CONSTRUCTORDESTRUCTORA Constructor is used to initializing the object of that classDestructor is used to destroy the previously created object of the classConstructor name is always the same as class name with no any return type.Destructor name also same as the class name without any return type, but with ~ (tilde) prefix.Constructor overloading is possible in a classDestructor does not allow overloading (it can only be specified once in a class).Syntax:class EmployeeCons{ EmployeeCons(){ } };Syntax:class EmployeeDestr{ ~EmployeeDestr(){ } };Constructor allocates the memory while creating an objectDestructor release the memory while destroying an object.15) What do you understand by pre-processor? What are different types of header files in C?The C pre-processor is used to scan and modify a source code before its compilation. The line starting with the symbol # followed by the directive name, in the source code, is known as pre-processor directive. Pre-processor directive invoked by the compiler to process some code before the compilation process.Each line in code can have a single pre-processor directivePre-processor directive does not include a semicolon at the end.Header files are the files which contain macro definitions and functions definition. It used with pre-processor directives with a file extension of ".h." There are two types of header files in C:System header files: These header files come with the compilerUser-created header files: These files are written by the programmer.Following are some mainly used header files in C#include#include#include#include#include, and many more.16) What are some DBMS packages?There are some built-in DBMS packages provided by Oracle. With the help of Oracle DBMS packages, we can create various Oracle applications.Following are some basic packages provided by Oracle:Oracle dbms_alertOracle dbms_application_infoOracle dbms_aqadmOracle dbms_cryptoOracle dbms_fgaOracle dbms_jobOracle dbms_job.submitOracle dbms_lobOracle dbms_metadataOracle dbms_monitor17) Differentiate between compiler and interpreter?A computer can only understand the code written in binary form, i.e., in the form of 0's and 1's, Therefore, to communicate with the computer we need to convert our code (source code) into machine code. And the compiler and interpreter both are the computer programs which convert a programming language from source code to machine code. The main differences between both of the translator are given below:CompilerInterpreterA compiler is a software program that converts a high-level language source code into a low-level language machine codeThe interpreter is a software program that is used to directly execute a source code written in a high-level programming languageIt creates an intermediate source code.It does not create any intermediate code.A Compiler converts the source code completely at a timeInterpreter converts the source code line by line at a time.A compiler converts source code in one go, hence these are faster.As interpreter converts a source code line-by-line, hence these are slower as compare to the compiler.Finding an error is difficult.Finding an error is easy.Used for the languages C, C++, C#, Scala, etc.Used for languages Java, PHP, Perl, Python, etc.18) What type of operation can be performed using stack and queue in Data structure?Organization of data in the computer can be done with the help of data structure so that data can be accessed easily and efficiently. There are different types of data structure used in computer, and two of them are Stack and Queue data Structure.Stack: A stack is a type of linear-data structure, which logically represents and arrange the data in the form of a stack. As a real-life example of a stack is "plates arranged in the form of the stack." In a stack structure, any operation can be performed on data items from one end only.A Stack structure follows a particular order for operation on data items, and that order can be LIFO (Last in First Out) or FILO (First in Last Out). A stack can be represented in the form of an array.Types of Operations performed on Stack:1. Push: Push is an operation that can be performed, to add an element in the stack.As in the above diagram, the top element was 93 (before addition of a new element), and after performing PUSH operation, a top element is 10. Now pointer will point at the top of the stack.2. Pop: If we try to remove or delete an element from the Stack, then it is called as Pop operation.As in the above diagram, if we want to delete an element from the top of the Stack, then it can be done by the Pop operation.3. isEmpty: If we wanted to check whether the stack is empty or not, then we can perform an isEmpty operation. It will return three values: If we will perform a Pop operation on empty Stack, then it is called underflow condition.Empty-1Single element present0Stack is fullN-1Stack overflowN4. Peek or Top: If we perform Peek operation it checks all the elements of the stack and returns the top element.Queue: A Queue is an ordered collection of data elements same as a stack, but it enables insertion operation from one end called as REAR end and deletion operation from other end called as a FRONT end.A Queue structure follows an order of FIFO (First in First Out) for insertion and deletion of the data element.Real life example of a queue is people waiting to buy a movie ticket in a line.Types of Operations performed on Stack: The two main operations which can be performedOn Stack are Enqueue and Dequeue.Enqueue:This operation is performed to add an element in the queue at the rear end. After adding an element in a queue, the count of Rear pointer increased by 1. Below is the Array representation of queue with Enqueue operation. Dequeue:This operation is performed to remove an element from the queue at the front end. After removing an element from the queue, the count of Front pointer gets decremented by 1. Below is the diagram which shows the removal of the data element from a queue.Other operations performed on the queue are:Peek: This operation is used to get all the data elements of queue without deletion of an element, at the front end.Isfull: This operation is performed to check whether a queue is full or not.Isempty: This operation is performed to check whether a queue is empty or not.19) What is use the of fprintf and fscanf?(C)Function fprintf(): In C language this function is used to write the character, integer, and String values into a single file.Syntax:int fprintf(FILE *stream, const char *format, ...) ; Where stream= file pointer of datatype "FILE". Format can %d, %s, %f, etc. Example:#include #include int main () { FILE * fp; //file pointer fp = fopen ("file.txt", "w"); Opening file fprintf(fp, "%d %s %s %s", 12, "rollno", "student", "present"); //writing data of different format fclose(fp); //file closing return(0); } Output:12 rollno student present Function fscanf(): In C language fscanf() function is used to read set of characters or mixed data from the file.int fscanf(FILE *stream, const char *format, ....); Where stream= file pointer of datatype "FILE". Format can %d, %s, %f, etc. 20) What is a linked list? Explain its applications?A Linked list is a linear data structure similar to an array, which is used to store the data in an organized way.In Linked list data elements are not stored in contiguous blocks.Applications of the Linked list:A linked list can be used for implementations of stacks and queues.Implementation of graphs can be done using the linked listA linked list can be used for dynamic memory allocationA linked list can be used for implementation of graphIt can be used for performing arithmetic operations on long integers.A linked list can be used with the music player for playing the songs.21) How C++ is more advantageous as compared to C?C and C++ both are the computer programming languages. Both the languages enable us to write efficient code. As C++ is an advanced version of C language, therefore it has some extra features than C languages. The main advantages of C++ over the C language are given below:As C++ is an object-oriented language, hence support the function overloading, whereas C language does not support function overloading.C++ provides the property of data hiding, whereas C does not provide this featureC++ supports exception handling, whereas C does not support the exception handling conceptC++ provides a concept of classes and objects, wherein C language there is no such concept.22) Which is the smallest package in Java API?The smallest package in Java API is java. applet package.23) What are searching techniques? Explain the linear search?Searching is the process of finding the value or place of a data element in a given list. A searching technique will be successful if the data element are found else it will be unsuccessful. There are primarily two types of standard searching techniques, which are:Linear search or Sequential searchBinary SearchLinear search: Linear search technique is the easiest way of searching an element. We can perform a linear search operation in both sorted and unsorted list (usually an array list). To understand the linear search, let's take an example of an array list of 8 elementsExample:Input: a [ ] = {10, 140, 589, 20, 89, 78, 90, 110} x= 90; Output: 6. The Basic algorithm for linear search:Step 1: Traverse the array list.Step 2: Match the key element with all elements present in the arrayStep 3: if key element found, return the index position of an element in the array listStep 4: If the key element does not found, return -1Implementation of linear search using Java program:public class LinearSearchExample { public static int linearSearch(int[] arr, int key) { for(int i=0;i

In April 2018, TCS became the first Indian IT company to breach $100 billion market capitalization.56.6M1KHTML TutorialRecruitment ProcessTCS conducts generally 3 rounds to select fresher as Software Developer in their organization.Aptitude testTechnical interviewHR interviewThe recruitment drive starts with a written test followed by a one on one interview. They may also conduct a group discussion for some students. Sometimes they waive the written test for students above aggregate of 75, and they were allowed to appear directly for the interview without a written test.In the technical round, fresher candidates are generally asked questions on their final project and a single technology in which they are trained.Academic Criteria65 percent or above in B.Tech, Class X and XII.No backlogs at the time of interview Technical Interview Questions1) Explain the functionality of linked list.A linked list consists of two parts: information and the link. In the single connected listening, the beginning of the list is marked by a unique pointer named start. This pointer does point to the first element of the list and the link part of each node consists of an arrow looking to the next node, but the last node of the list has null pointer identifying the previous node. With the help of start pointer, the linked list can be traversed easily.2) What are the four basic principles of OOPS?The four basic principles of Object-Oriented Programming System are listed below:Abstraction: Abstraction is a process of hiding the implementation details and showing only functionality to the user. For example, sending SMS where you type the text and send the message. You don't know the internal processing about the message delivery.Abstraction lets you focus on what the object does instead of how it does it.Inheritance: Inheritance in Java is a mechanism in which one object acquires all the properties and behaviors of a parent object.Encapsulation: Encapsulation in Java is a process of wrapping code and data together into a single unit, for example, a capsule which is mixed of several medicines.Polymorphism: Polymorphism in Java is a concept by which we can perform a single action in different ways. Polymorphism is derived from 2 Greek words: poly and morphs. The word "poly" means many and "morphs" means forms. So polymorphism means many forms.3) What is inheritance?In, Object-Oriented Programming, inheritance is a mechanism based on classes.Inheritance refers to inhering the data members and properties of a parent class to a child class. A class which is derived from another level is often called as a sub-class or a child class, and the type from which the child class is obtained is known as super-class or parent class.4) What is the way of inheriting variable of one class to any other class?//Base Class class A { public int a; } //Derived Class class B : A { a=15; } 5) What is Polymorphism?Polymorphism is a concept in OOPS which means having many forms. In simple words, it means that different actions will be performed in different instances. Polymorphism is of two types:Method overloadingOperator overloading6) What are the different types of inheritance?Types of Inheritance:Single inheritanceMultiple InheritanceMulti-level InheritanceMulti-path InheritanceHierarchical InheritanceHybrid Inheritance7) What is the difference between classes and interface?The differences between classes and interfaces are listed below:A class can be instantiated by creating its object, whereas interfaces cannot be instantiated as all the methods in the interface are abstract and do not perform any action, so there is no use of instantiating an interface.A class is declared using class keyword whereas an interface is declared using interface keyword.The members of the class can have access specifier such as public, protected, and private but members of the interface can not have the access specifier, all the members of the interface is declared as public because the interface is used to derive another class. There will be no use to access specifies inside the members of an interface.The methods inside the class are defined to perform some actions on the fields declared in the class whereas interface lacks in asserting in areas, the ways in an interface are purely abstract.A class can implement any number of the interface but can only extend one superclass. Whereas interface can reach any number of interfaces but cannot perform any interface.A class can have a constructor defined inside the class to declare the fields inside the class, whereas interface doesn't have any constructor defined because there are no fields to be initialized.8) What is software development life-cycle?Software development life-cycle is steps involved in the life cycle of software development phase. Generally, it is followed by the development team which develops the software in the organization. It consists of a clear explanation of developing and maintaining the software.9) What is normalization of databases, joins, and keys?Normalization is process of organizing data in a database efficiently. Two goals of the normalization process are: to eliminate redundant data (for example, storing the same data in more than one table) and also ensure data dependencies make sense (only storing related data in a table). These both are important as they reduce the amount of space a database consumes and ensure that data is logically stored.10) What are loops?Loops are used to execute block of statement several times in a program depending upon the conditional statement. The basic structure of a circuit is given above in the diagram. For each successful execution of the loop, the conditional statement should be checked. If the conditional statement is true, then the circuit will be executed. If the conditional statement is false, then the course will be terminated.11) Explain about Joins, Views, Normalization, Triggers?The JOIN keyword is used in an SQL statement to query data from two or more tables, based on a relationship between specific columns in these tables.Tables in a database are often related to each other with keys.A view is a virtual table. A look contains rows and columns, just like a real table. The fields in a picture are fields from one or more real tables in the database.You can add SQL functions, WHERE, and JOIN statements to a view and present the data as if the data were coming from one single table.12) List different advantages of DBMSImproved data sharing.The list of several advantages of DataBase Management System:Improved data security.Better data integration.Minimized data inconsistency.Improved data access.Improved decision making.Increased end-user productivity.13) What is Database Management System?A DataBase Management System is a software system used for creating and managing databases. DBMS make it possible for the end user to build and maintain databases. DBMS provides an interface between the end user/application and the databases.14) What is database Schema?The formal definition of the database schema is a set of formulas (sentences) called integrity constraints imposed on a database.15) What are the conditional statements?The conditional statements can alternatively be called as conditional expression also. Conditional comments are the set of rules which were executed if a particular condition is true. It is often referred to an if-then statement because if the state is true, then the statement is executed.16) What is the difference between the foreign key and reference key?Reference Key is the primary key that is referenced in the other table (linked via the other tables Foreign Key). Foreign Key is how you connect the second table to the primary tables Primary Key (or Reference Key).17) What is the difference and similarity between C and C++?C++ has classes whereas C did not have classes.C does not support function overloading. In C, for input or output, we use functions like gets(), puts(), scanf(), printf(), etcC does not support exception handling.18) The structural difference between bitmap and b-tree index?BtreeIt is made of branch nodes and leaf nodes. Branch nodes hold prefix key value along with the link to the leaf node and the leaf nodes contain the indexed value and rowed.BitmapIt consists merely of bits for every single distinct value. It uses a string of bits to locate rows in a table quickly. It is used to index low cardinality columns.19) What is the difference between a Clustered index and non-clustered index?Clustered IndexOnly one per tableFaster to read than non clustered as data is physically stored in index orderNon-Clustered IndexCan be used lot of times per tableQuicker for insert and update operations than a clustered index20) Diffrentiate between socket and session?Socket is the Combination of IP address and Port Number (in pairs)The session is a Logical Connectivity between the source and destination.21) What is an array?An array is a collection of similar elements. For an array, the necessary condition is that the data type of all the elements in the array must be same. The declaration of an array in C++ is as follows:int a[10];This defines an array whose name is a and has ten elements from index 0-922) Given an array of 1s and 0s arrange the 1s together and 0s together in a single scan of the array. Optimize the boundary conditions. #include #include void main() { int A[10]={'0','1','0','1','0','0','0','1','0','1','0','0'}; int x=0,y=A.length-1; while(x x++; else if(A[y]) y--; if(A[x] && !A[y])//here we are checking that stating index is having 1 and last index having 0 than swap values A[x]=0,A[y]=1; } getch(); } 23) Define Data Abstraction. What are their importance?Abstraction is process of recognizing and focusing on essential characteristics of a situation or object and leaving/filtering out the unwanted components of that situation or object.Abstraction is the basis for software development. It's through this concept we define the essential aspects of a system. The process of identifying and designing the ideas for a given system is called Modeling ( objectmodeling).Three levels of data abstraction are:Logical level: Information stored in the database. e.g., Database administratorPhysical level: Where data is stored physically in the database.View level: End users always work on view level. If any amendment is made it may be saved by another name.24) Write a function to swap two numbers without using a temporary variable.void swap(int &i, int &j) { i=i+j; j=i-j; i=i-j; } 25) Memory Allocation in C/C++The calloc() function allocates a memory area; the length will be the product of its parameters (it has two settings). calloc fills the memory with ZERO's and returns a pointer to the first byte. If that fails to locate enough space, it returns a NULL pointer.A malloc() function allocates a memory area; length will be the value entered as parameter. (it has one parameter). It does not initialize memory areaThe free() function is used to free the allocated memory(allocated through the calloc and malloc), in other words, this used release the allocated memorynew also used to allocate memory on the heap and initialize the memory using constructordelete also used release memory allocated by new operator26) Write output of the program?int i=10; printf("%d%d%d",i,++i,i++); Answer= 10 12 1227) what is virtual function and pure virtual function?Virtual function:- To achieve polymorphism, function in base class is declared as virtual. By state virtual, we make a base class pointer to execute the purpose of any derived class depends on the content of pointer (any acquired class address).Pure Virtual Function:- This is the function used in base class, and its definition has to be provided in derived class, In other pure virtual function has no definition in the base is declared as :virtual void fun()=0; It means that this function is not going to do anything, In case of pure virtual function derived function has toimplement a pure virtual function or redeclare it as a pure virtual function28) What are WPF and WCF?WPF/WCF application, need in .NET 3.0 Framework. These application will cover the following concepts:WCF(Windows Communication Foundation)The new service orientated attributesThe use of interfacesThe use of callbacksAsynchronous delegatesCreating the proxyWPF( Windows Presentation Foundation )StylesTemplatesAnimationsDatabinding29) Write a program in C to swap two numbers without help of a third variable. /* * C++ program to swap two numbers without using a temporary variable */ #include using namespace std; /* Function for swapping the values */ void swap(int &a, int &b) { b = a + b; a = b - a; b = b - a; } int main() { int a, b; cout a >> b; swap(a, b); cout

It may be Parameterized or Default. If the user does not define a constructor within a class, the default constructor is always included in that code.The objective of Constructor is to initialize an object called object initialization. Constructors are mainly created for initializing an object.2) How Java enable High Performance?Java uses a Just-In-Time Compiler to enable high performance. Just-In-Time Compiler is a program that turns Java bytecode, which is a program that contains an instruction that must be interpreted into instruction that can be sent directly to the processor.3) Why is java considered as dynamic?It is designed to change the evolving environment. Java can carry an extensive amount of runtime information that can be used to verify and resolve access to the object at runtime.4) What is joins in SQL?Joins is nothing but connecting two or more table to fetch the record from two or more databases.5) Can we have Private Constructor in Java?Private Constructor is used if you do not want other class to instantiate the object. Private Constructor is used in Singleton design Pattern, Factory Method Design Pattern.6) Differentiate Between Primary Key and Unique Key.Primary KeyUnique Key1. In a Primary key, there should be only one primary key in a table.1. In A Unique key, there can be more than one unique key in a table.2. Primary key will block duplicate value and a null value.2. Unique key will block duplicate value and accept a null value.7) Differentiate between Method Overloading and Method Overriding.Method OverloadingMethod Overriding1. Method Overloading is used to gain the readability of the program.1. Method Overriding is used to provide the specific implementation of the method that already provided by the superclass.2. In the case of Method Overloading, the parameter must be different.2. In the case of Method Overriding, the parameter must be equal.3. Overloading happens at Compile time.3. Overriding happens at runtime.4. The Return type of method does not matter in case of method overloading it can be the same or different.4. In the case of method Overriding, the return type must be the same.5. you can overload a static, final and private method in Java5. You cannot override a static, final and private method in Java.8) What is the purpose of finalize () method in Java?Finalize () method in java is a special method much like the main method in java. Finalize () method is called before garbage collector reclaims the object, its last chance for any object to perform clean up activity i.e. releasing any fixed order resources held, terminating connection if open etc.9) Why can static method not override?A static method cannot override because the static method is bound with class whereas instance method is bound with an object. Static method belongs to the class area and Instance method belong to the heap area.10) What is singleton Class?Singleton Class limited the number to one but allowing the flexibility to create more object if the situation changes.11) Can we override java main method?No, because main is a Static Method.12) What is Class Cast Exception?Class Cast Exception is thrown by java when you try to cast an object of one data type to another data type. Java allows us to cast the variable of one type to another as long as the casting happens between compatible data type.13) Why polymorphism is used in Java?The good reason for why polymorphism is a need in Java because the concept is extensively used in implementing inheritance. It plays an important role in allowing the object having a different internal structure to share the same external interface.14) What is an Abstract class?An Abstract class is one that is not used to create an object. It is only used as base class for the other class. The Abstract class is always public or friendly.Syntax:public abstract class class_name { //class member } 15) Can I have Private Constructor in Abstract Class?Abstract Class can have Private Constructor But that class cannot be extended by another class. Alternatively, of adding a static inner class inside the Abstract Class and extends that Abstract Class.HCL HR Interview Questions1) Tell us about yourself.This is the most common questions asked for both fresher's as well as experienced candidates.

Some of the coding questions are given below for practice.1) Write code to reverse the linked list?#include #include struct Node { int data; struct Node* next; }; /* Function for reversing the linked list */ static void reverseList(struct Node** head_ref) { struct Node* t2 = NULL; struct Node* start = *head_ref; struct Node* t1 = NULL; while (start != NULL) { t1 = start->next; start->next = t2; t2 = start; start = t1; } *head_ref = t2; } void newNode(struct Node** head_ref, int new_data) { struct Node* new_node = (struct Node*) malloc(sizeof(struct Node)); new_node->data = new_data; new_node->next = (*head_ref); (*head_ref) = new_node; } /* Function to print linked list */ void printList(struct Node *head) { struct Node *temp = head; while(temp != NULL) { printf("%d ", temp->data); temp = temp->next; } } int main() { struct Node* head = NULL; newNode(&head, 20); newNode(&head, 14); newNode(&head, 30); newNode(&head, 68); printf("Input linked list\n"); printList(head); reverseList(&head); printf("\nReversed Linked list \n"); printList(head); } Output:Input linked list 68 30 14 20 Reversed Linked list 20 14 30 68 2) Write a code which multiplies two numbers using the minimum number of additions.#include int main() { int product=0, x, y, n; x=10; y= 20; for(n = 0; n Before swap 20 30 After swap 30 20 4) Write a program to calculate the nth term of the Fibonacci series?#include int fun(int n) { if (n >1; } total_bits=count_onebit+count_zerobit; printf("Total bits are=%d Total zero bits are=%d Total one's bits are= %d", total_bits, count_zerobit, count_onebit); } Output:Total bits are=4 Total zero bits are=0 Total one's bits are= 4 6) Write an algorithm to compute the output for X^N, having complexity log n.#include int pow(int x, int n) { int y; if( n == 0) return 1; y = pow(x, n/2); if (n%2 == 0) return y*y; else return x*y*y; } int main() { int x = 6; int n = 3; printf("The output for x^n, where x=%d, n=%d, %d", x, n, pow(x, n)); return 0; } Output:The output for x^n, where x=6, n=3, 216 7) Write code to check a binary tree is BST tree or not?public class CheckBST { public static Node prevNode = null; //Method1: public boolean isBST1(Node root) { if (root != null) { if (!isBST1(root.left)) return false; if (prevNode != null && prevNode.data >= root.data) { return false; } prevNode = root; return isBST1(root.right); } return true; } //method 2 public boolean isBST2(Node root, int min, int max) { if (root != null) { if (root.data > max || root.data 10 Andhra Pradesh 2) Why we use sprint() function?sprint() is a C library function which is termed as "string print." sprintf function is used to hold the formatted data output as String.Syntax:int sprintf (char *string, const char *form, .... ) Example:#include int main() { char string[50]; int a = 10, b = 5, c; c = a * b; sprintf(string, "multiplication of %d and %d is %d", a, b, c); printf("%s", string); return 0; } Output:multiplication of 10 and 5 is 2 3) How to differentiate between char a[]= ?String and char*a =?String.The statements:Char a[ ]= "computer";char *a= "computer";The difference between the above two statements is that the first statement will create an array of 9 elements will automatically add the null pointer and the size of array 'a' will be 9.But the second statement will create a pointer variable. We cannot perform any array operation on this pointer variable as it will be stored in read-only mode.Example:#include int main() { char a[] = "Computer"; printf("%lu", sizeof(a)); a[1] = 'n'; printf("\n%s", a); return 0; } Output:9 Cnmputer Example 2#include int main() { char *a = "Computer"; printf("%lu", sizeof(a)); return 0; } 4) Explain Data breakpoints? Where can we use this?Data Breakpoint is a strong feature available for C++, which allow us to stop the execution when the value stored at a particular memory location changes. Data breakpoints can be used to solve the memory corruption issue.5) Differentiate between new and malloc()?The new and malloc() both are used for dynamic memory allocation. But there are various differences between new and malloc, which are given below,new is an operator in C language, whereas malloc() is a function for memory allocation.new operator calls the constructor, whereas malloc() does not call the constructor.The memory allocated from the "free store" by new operator, whereas memory allocated from the heap by malloc() function.On failure of execution, new operator throws an exception, whereas malloc() returns Null.new operator does not require the sizeof() operator, malloc() function requires the sizeof() operator to know the memory size.6) Differentiate between process and thread?Following are the basic differences between the process and the thread:The Process is an execution of a program, whereas thread is a lightweight process.A Process does not share the resources like memory, whereas thread can share the resources.The Process takes more time for context switching, whereas thread requires less time for context switching.The Process is less efficient as compared to a thread in terms of communication.7) What is C++ Shorthand property? What is its role?C++ provides shorthand property, which enables a programmer to use the assignment operator in a shorter way.Example:x=x+5; can be written as x+=5 using shorthandx=x-10; can be written as x-=10;8) What do you understand by function prototype declaration and definition?Function prototype declaration: function prototype declaration statement gives the following information about the function:It tells the symbolic name of the functions.Information about the return type of function.Information about the argument passed as input with their datatypes.Example:int add(int a, int b, int c) Where add is the name of a function, and a, b and c are the passed arguments.Function definition: The function definition is the actual source code of the function. Function definition gives information that what that function actually does.Example:int add(int a, int b, int c){ c= a + b; return c; } 9) What do you understand by Conditional Operators?Conditional operators are ternary operators with three operands, which are used as shorthand in place of the if-else statement.Conditional operators return the first expression if the condition is true and return second expression if the condition is false.Syntax:(Check expression)? Expression1: Expression2; Example:var = (x The primary protocols used at this level are:IP (internet protocol): This protocol is responsible for forwarding the packets from source host to destination using an address which is consisted by packet header. IP has two main versions IPv4 and IPv6.ICMP (Internet control message protocol): This protocol is mainly responsible for informing the problem in the network.ARP (Address resolution protocol): ARP protocol is an essential protocol of the TCP/IP model, and it is responsible to resolve an IPv4 address to physical address.3. Transport Layer: This is the third layer of the TCP/IP model, which is responsible for the communication between the source host and destination host and error-free data transmission.This layer consists of mainly two protocols:TCP (Transmission Control Protocol): TCP is a reliable protocol for error-free communication between the source and destination host. It's a connection-oriented protocol.UDP (User Datagram Protocol): This protocol is not reliable as compare to TCP protocol, we can use this protocol which does not require reliable communication. It is a connectionless protocol.4. Application layer: This is the top layer of the TCP/IP model. It describes the application protocol and provides node-to-node communication.This layer contains various higher level protocols which are:HTTP and HTTPs(Hypertext transfer protocol)FTP(File transfer protocol)SSH( Secure Shell)TFTP(Trivial file transfer protocol)SMTP(Simple mail transfer protocol)DHCP(Dynamic host configuration protocol)2) Explain the working of the stack while calling a function? When stack overflow occurred?The Stack is a particular area of RAM, just like as Heap. But stack is used to store local variables, parameters and return values used inside a function and stack stores and deallocates memory automatically.When we call a function, stack performs following steps:Push space for the return variables.Push parameters in the stack.Push the local variable of the function.When we call a function, stack adds a stack frame which consists space for actual parameters, local variables, return address, etc. This stack frame lives in active frame till the time function is being called, and once execution finishes then stack remove that stack frame from the stack.Stack Overflow: As we know that stack deallocated the memory and free up space after execution but still there is a condition when complete stack space used, and there is no more space to save the variables, so this is called stack overflow. It occurs because the space size of the stack is also limited in size, and at the time of execution if we allocate more memory than available memory than overflow occurred and the program got crashed. Some example for stack overflow are:Use of Infinite recursionUse of very large stack variableUse of very deep recursion3) Explain the meaning for the declaration: int*const p & const int* const p?int * const p: By declaring a pointer in such a way that means we are declaring point variable p as constant, which cannot be changed. We cannot change the address its holding, or it cannot point to other variables. If we try to change the address of p, then it will give a compile time error.const int * const p: By declaring a pointer in such a way means, we cannot change the address of the pointer as we as we cannot change the address at that address. If we try to do it, then it will generate a compile time error.4) What are default functions in C++C++ provides the six default member functions which are given below:Default constructorDestructorsCopy constructorsCopy assignment operatorsMove constructorsMove assignment operators5) Which data structure is used for the dictionary?To implement a dictionary, which type of data structure should be used depends on what we required, there are some following data structure which can be used for implementation of the dictionary.Hash-table: If we want a simple dictionary with no option for the prefix, or nearest neighbour search then we can use Hashing or Hashtable for the dictionary.Trie: It can be a good option if we want to add prefix and fast lookup. But, it takes more space than other data structures.Ternary Search Tree: If we want all the qualities like trie but do not want to give the more space then we can use ternary search tree.BK-tree: BK-tree is one of the best data structure if we want specifications like spell checker, find the similar word, etc.6) How can you find a unique word from a String which also has duplicate words?We can find the unique word from a string by using HashMap, Set and Regex.Candidate can also be asked for questions like:Implement Snake and Ladder game and find the minimum number of moves required to reach from 1 to 100 in a given game, using Dynamic Programming.Model a data structure for a DFA that takes an event as parameter and performs a desired action.Solve the three mislabelled jars problem.How to compare two binary trees?How to prove that in a tree the number of internal nodes is one less than leaves?Technical third round or director RoundThis round is a challenging round as in this round the manager ask the questions based on your projects, so candidate must have in-depth knowledge about their project which they have done and some problematic puzzles which candidates needs to solve.1) Write an algorithm for the tower of Hanoi?Tower of Hanoi is a very popular mathematics puzzle. In this puzzle, we are given three disk and three rods. Disks are arranged in the first rod like a stack, in ascending order. We need to transfer the disk from the first rod to third in the same order.There are some rules as well:We can move one disk at one timeWe can only move the uppermost diskDisk always should be in ascending order, i.e., a bigger disk cannot put on a smaller one.Algorithm:Let's suppose there are thee towers Beg, Aux, and Dest, and there are two disks where n disk is larger disk and n-1 is smaller one.StartStep 1: shift n-1 disk from tower Beg to AuxStep 2: shift n disk from Beg to EndStep 3: shift disk n-1 form tower Aux to C.Tower(n, Beg, Aux, Dest) Begin If n=1 then, Print: Beg-> Dest; else Call Tower(n-1, Beg, Dest, Aux); Call Tower(n, Beg, Aux, End); Call Tower(n-1, Aux, Beg, End); endif End 2) Write a code to find the loop in a Linked list? How will you remove this loop?#include #include struct Node { int data; struct Node* next; }; /* Function for removing the loop. */ void remLoop(struct Node *, struct Node *); /*Function to remove and detect the loop*/ int detAndRemLoop(struct Node *list) { struct Node *p1 = list, *p2 = list; while (p1 && p2 && p2->next) { p1 = p1->next; p2 = p2->next->next; /*if p1 and p2 will meet at some point which means there is a loop*/ if (p1 == p2) { remLoop(p1, list); printf("Loop is occurred\n"); /* Return 1 if loop is found */ return 1; } } /* Return 0 if there is no loop*/ return 0; } /* Function to remove loop. */ void remLoop(struct Node *loop_node, struct Node *head) { struct Node *ptr1 = loop_node; struct Node *ptr2 = loop_node; // Count the number of nodes in loop unsigned int k = 1, i; while (ptr1->next != ptr2) { ptr1 = ptr1->next; k++; } // Fix one pointer to head ptr1 = head; ptr2 = head; for (i = 0; i next; while (ptr2 != ptr1) { ptr1 = ptr1->next; ptr2 = ptr2->next; } ptr2 = ptr2->next; while (ptr2->next != ptr1) ptr2 = ptr2->next; /* Set the next node to Null to fix the loop */ ptr2->next = NULL; } /* Function to print linked list */ void printList(struct Node *node) { while (node != NULL) { printf("%d ", node->data); node = node->next; } } struct Node *newNode(int key) { struct Node *temp = (struct Node*)malloc(sizeof(struct Node)); temp->data = key; temp->next = NULL; return temp; } int main() { struct Node *head = newNode(40); head->next = newNode(15); head->next->next = newNode(12); head->next->next->next = newNode(10); head->next->next->next->next = newNode(4); /* Create a loop*/ head->next->next->next->next->next = head->next->next; detAndRemLoop(head); printf("Linked List after removing loop \n"); printList(head); return 0; } Output:Loop is occurred Linked List after removing loop 40 15 12 10 4 3) How will you design a data structure for excel spreadsheets?We can design an excel spreadsheets by using:Two-dimensional array ( but it will take lots of space)Sparse matrixMap, etc.4) Explain memory protection in OS.Memory protection is a mechanism which controls the unauthorized access of memory in the computer. Memory protection prevents the unallocated memory access by a process. Memory address is first checked before used by a process, to see whether it is allocated address or not.There are two registers LBR and UBR are used to implement memory protection.5) What is Virtual Memory in OS?Virtual Memory is memory management technique of Operating System. Virtual memory is an extra space provided to a program when a main memory does not have the sufficient space to execute a code. It temporarily transfers data from RAM to disk storage, which uses inactive memory of hard disk, which is termed as Virtual Memory.6) Write an algorithm to insert an element into a sorted linked list?Suppose the linked list is sorted in ascending order then following is the algorithm for the same. Let the input node is 13 and let assign as nSuppose Input linked list is:3 8 11 15 20 1) If given linked list is empty then assign the node as head and return it.2) If value of the node n is less than value of head node, then insert the node at start and assign it as head.3) In a loop, search the appropriate node after which the input node is to be inserted. To search the appropriate node start from head, keep moving until you reach a node x(Let?s suppose 15)whose value is greater than the input node. The node before the x will be the appropriate node(11).4) Insert the node(13) after the appropriate node(11) found in step 3.After insertion:3 8 11 13 15 20 7) Find pair of elements whose sum equal to a given number?#include void Pair(int arr[], int n, int sum) { for (int i = 0; i
