C++ Introduction

C++ is an object-oriented programming language. It was developed by Bjarne Stroustrup at AT&T Bell Laboratories. It is superset (extension) of C programming language.

Depending upon features supported by programming languages, they are classified into two different categories:

  1. Object-based programming languages
  2. Object-oriented programming languages

Object-based programming language

The language that supports programming using objects is called object-based programming language. Important features of object-based programming languages are:

  • Data encapsulation
  • Data hiding
  • Operator overloading
  • Automatic initialization

Object-oriented programming language

Object-oriented programming supports the features of object-based programming along with inheritance and dynamic binding.

C++ fully supports object-oriented programming. To understand Object-Oriented programming, we need to know the concept of a major pillar of it:

  1. Object
  2. Class
  3. Data abstraction
  4. Encapsulation
  5. Polymorphism
  6. Inheritance
  7. Dynamic binding
  8. Message passing

C++ is not a pure object-oriented language. Object-oriented means working with object and class, but in C++ program can be written without using class.

C++ Usages

C++ program is applied in a large number of different sector. Some of them are as follow:

  • Windows System
  • Real-time system
  • Object-oriented database
  • Artificial Intelligence
  • Device driver etc.

C++ Example

We have given online editor option with each C++ example. So, you can edit any example and see the changed output.



To learn C++, you must have knowledge of computer fundamentals only.


This C++ tutorial is written to help beginners and professionals.
