Cognizant Genc Technical Interview Questions for Freshers

1. What do you understand by Pointers in C language?

A Pointer is a variable which stores the address of another variable. It is used to point to the variables indirectly. 

2. What do you understand by Memory Leaks?

Memory Leaks occur when objects available in a heap are not utilised. The garbage collector fails to remove it from memory. It also leads to performance issues.

3. What algorithm is used in Garbage Collection?

The most used Garbage Collection algorithm is Mark and Sweep algorithm.

If you want to enrich your career and become a professional AWS Database Developer, then enroll in "AWS Database Training" - This course will help you to achieve excellence in this domain.

4. Can you explain Mark and Sweep algorithm?

Mark and Sweep algorithm is a garbage collection algorithm. It works in 2 phases.

In the first phase, the algorithm detects the unused objects in the memory, while in the second phase, these objects are removed from the memory to reclaim the wasted space.

5. What do you understand by Dangling Pointer?

Pointers that are not initialised with a valid address are called dangling pointers. It occurs during the object destruction phase. The object is destroyed from memory, but the pointer's address is not changed.

6. What do you understand by Recursion?

Recursion happens when a program calls itself.

7. What do you understand by a Data Type?

A Data Type is characteristic of the data. It helps the machine understand how the machine will use the data in the code.

The malloc() function is used for memory allocation. This function is used to allocate the memory dynamically.

ptr = (cast-type*) malloc(byte-size)

9. What do you mean by a string?

The string is a data type. It is used to represent a sequence of characters.

10. What do you mean by an array?

An array is a collection of similar elements stored in the continuous memory block. The data stored in the memory can be accessed by index.

A major difference between an Interpreter and a Compiler is that the former translates one code at a time while the latter scans the entire code at one go.

15. Define Abstraction, Inheritance, Encapsulation, and Polymorphism.

  • Abstraction means only displaying what is necessary while hiding all the unnecessary data and implementation from the end-user.
  • Inheritance is a mechanism that allows one object to acquire all the characteristics and properties of another object. 
  • Encapsulation is used to protect the data from the outside world. It shields the data by wrapping it under a single program or function.
  • Polymorphism means taking multiple forms. The object in the program can act in different ways depending on the message or the event occurring.

No, you cannot override a constructor in Java. If you try to call a super class’s constructor in a subclass, the compiler treats it as a method and will show compilation error.

Construct Overloading refers to having multiple constructors with different parameters so that every constructor can perform a different activity.

19. Define Virtual Functions. What are the rules before executing it?

A Virtual Function is a member function that is declared in the base class and it is overridden by the derived class. It helps in achieving runtime polymorphism. Following are three rules to keep in mind before executing Virtual Functions:

  • Virtual Functions cannot be static
  • Virtual Functions should be accessed using a pointer or reference to the base class.
  • A class can have a Virtual Destructor but not a Virtual Constructor.

20. What do you understand by DML and DDL statements?

DML stands for Data Manipulation Language. These are used to manipulate the database objects inside the database. Insert, delete, and update are included in DML statements. DDL stands for Data Definition Language. These are used to define or modify objects in the database. Create, Alter, Drop, and Truncate are included in DDL statements.

public class powerNumber {  
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);    
    }  
} 



23. Write a code to reverse a number 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);  
    }  
}  

24. What is a Linked list? 

Linked List is like an array; it is a collection of elements in a linear fashion. The order of the elements is determined by the pointer. This pointer points to the next element in the collection. 

25. Can you reverse a Linked List? Explain.

Yes. We can reverse a linked list. Here is how:

Initialize three-pointers prev as NULL, curr as head and next as NULL.
Iterate through the linked list.
In a loop, do the following. 
Before changing next of current, 
store next node 

next = curr->next

Now change next of current 
This is where actual reversing happens 
curr->next = prev 
Move prev and curr one step forward 
prev = curr 
curr = next

26. What is Queue? Explain with an example.

Queue is one of the most important data structures. Any queue follows the first in first out method. It means that the element that is inserted first gets removed first. The elements are inserted near the bottom end and deletion is done at the top end. A good example of a queue is the one for cinema tickets.

27. What do you understand by Doubly Linked List?

It is an advanced version of a simple Linked List. One can traverse forward and backwards using a doubly-linked list. Unlike a simple linked list, it stores the previous pointer as well.

Push() is used to insert the elements in the stack, while Pop() is used to remove the elements from the stack.

A Binary Tree is a non-linear data structure. Every node in the tree has left and right pointers along with data. They are used in Binary Search Tree Implementation. Also, they are useful in storing records without taking up much space

30. What do you understand by Dynamic programming?

Dynamic programming is a technique widely used in competitive programming where overlapping methods are used. The main problem is divided into smaller problems so that the results generated from solving them can be reused again.
