The class that the child class is derived is known as Super-Class or Parent Class.

4. What exactly is Polymorphism?

Polymorphism is a term used in OOPS which refers to having multiple types. Simply put it means that various actions can be carried out in various instances. The two kinds of polymorphism are:

  1. Method of overloading
  2. Operator overloaded

5. Types of inheritance?

Kinds of inheritance:

  1. Hybrid Inheritance
  2. Single inheritance
  3. Multi-level Inheritance

7. What are the four basic principles of OOPS?

The four principles that underlie the Object-Oriented Programming System are listed below:

  • Abstraction Abstraction is a method to hide the details of the implementation and only displaying features for the end user. For instance, sending an SMS in which you type the text and then send the message. The internal process that goes into the transmission of the message.
  • Polymorphism Polymorphism in Java is a term used to describe a way in which we can carry out an action in various ways. The word “polymorphism” comes from two Greek words that are Poly and Morphs. In Greek, the word “poly” refers to many, while “morphs” refers to forms. Therefore, polymorphism can refer to a variety of forms.
  • Abstraction allows you to focus on what the object is doing instead of what the thing does that.
  • Encapsulation The process of encapsulation within Java is the process of wrapping data and code into one piece, for instance, a capsule that is made up of a variety of medicines.
  • Inheritance Inheritance in Java is a method by where one object is able to acquire each of the property, properties and behavior of its parent object.

8.What’s the distinction between interfaces and classes?

The distinctions between interfaces and classes can be as follows:

  • A class is created by creating an object of it however interfaces are not instantiated since the methods of an interface have no meaning and don’t do anything, which is why there is no point in the creation of an interface.
  • A class is declared by using the keywords for classes, while it is called an interface by using interface keyword.
  • Members of the class may be granted access specifiers such as protected, public and private.
  • However, users of an interface do not be granted access specifiers and all members of the interface are classified as public since it is used by the interface to create from another class. There is no need for access specifiers within the interface’s members.
  • The methods within the class are designed to carry out certain operations on fields defined in the class, whereas the interfaces aren’t assertive in certain areas. The methods that interfaces work are abstract.
  • A class is able to implement any interfaces but only be extended by one superclass.
  • While interfaces can be extended to an unlimited number of interfaces, however it is not able to perform any interface.
  • A class may contain a constructor inside the class that declares the fields within the class, while an the interface does not have a constructor in place because there aren’t fields that need to be initialized.

Loops can be used to execute a the same block of code repeatedly in a program dependent on the conditional statements.

The fundamental layout of a circuit can be shown in the diagram above. After each successful completion in the loop, the conditional statements must be verified.

If it is found to be true it will continue to be completed. In the event that the statement does not match then the circuit will be canceled.

12. Explain about Joins, Normalization, Views,Triggers?

It is the JOIN keyword is utilized to create the SQL statement to retrieve data from multiple tables, based on the relationship between certain columns in these tables.

The tables in a database are typically linked to each using keys.

A view is an online table. The view contains columns and rows, just like a table. The fields displayed in a photograph are from one or more tables that are in the database.

an also add SQL statements, functions like WHERE and statements that JOIN one another to a view, and then display the data as though the data came from a single table.

19. Diffrentiate between socket and session?

Socket is the combination between IP address, Port Number (in pairs)

A session can be described as a logical Connection between the origin and the destination.

20. What is the difference between the foreign key and reference key?

Referral Key refers to the key used in the second table (linked through the foreign keys of the other tables Key). Foreign Key is the method of connecting the secondary tables Primary Key to primary table Key (or Primary Key (or Key Reference). Key).

21. The structural difference between b-tree index and bitmap ?


It is comprised of leaf nodes. Branch nodes contain the prefix key values as well as links to leaf nodes. the leaf nodes have the index value and are the rowed.


It’s a simple string of bits for each unique value. It makes use of an array of bits to identify rows in the table in a short time. It can be used to index columns with low cardinality.

22. What is the difference between a non Clustered index and-clustered index?

Clustered Index

  • One table per table
  • It is faster to read than data that is not clustered because the data is stored physically in order of index

Non-Clustered Index

  • It can be used many times per table
  • It is faster for insert and update processes than a clustered index.

23. What is an array?

The term “array” refers to a set of elements with similar properties. An array’s essential requirement is that the data type of the elements in the array have to be identical. An array declaration in C++ is as the following:

int a[10[10

This describes an array that’s name is an and contains 10 elements that are indexed from zero to nine

24. Memory Allocation in C/C+

Calloc() function allocates memory and the size will be the result of its settings (it has two options). calloc fills the memory using zero’s and then returns a pointer towards the initial byte. If it fails to find the space needed, it will return an NULL pointer.

The malloc() function allocates memory space; length will be determined by the value that is entered in the parameter. (it is a single parameter). It doesn’t start the memory area

Free() function utilized to free up the allocated memory(allocated by the calloc function and malloc functions) In other words, it is used to free the memory allocated

TCS CodeVita 2022

New technology is also utilized to allocate memory on the heap, and then initialize the memory with constructor

remove memory that was released previously allotted by the new operator

25. Define Data Abstraction. What is their significance?

Abstraction is the process that focuses attention and recognition on fundamental characteristics of a particular subject or event, and then filtering out undesirable aspects of the object or situation.

Abstraction is the base of software development. Through this notion, that we identify the most important elements of the system. The method of identifying and creating the concepts for a particular system is known as modeling ( modelling objects).

Three levels of abstraction of data are:

  1. Level of Logical information that is stored within the database. e.g., Database administrator
  2. Physical layer The the data is physically stored in the database.
  3. Level of view End users always work at the view level. If there is any change made, it can be saved with an alternative name.

26. What is the difference between virtual function and the pure function of virtualization?

Pure Virtual Function This is the function that is used in Base class. the definition is required to be defined in the class that is derived from it. other pure virtual functions, no definition in the base class. is defined as:

Virtual empty fun()=0;

This means that the function won’t accomplish anything, in the event the function is pure and virtual, the derived function must

Create a virtual function that is pure or declare it as an entirely virtual function

Virtual functions In order to attain polymorphism, the function of the base class can be declared virtual. Through state virtualization making an object of the base class to fulfill the function of any derived class dependent on the contents of the pointer (any purchased name of class).

27. What are WPF and WCF?

WPF/WCF applicationis required to be part of the .NET 3.0 Framework. This application will be able to cover the following aspects:
