Introduction to C++

C++ is an object oriented programming language developed by Bjarne Stroustrup at Bell laboratories.

An object oriented programming language focuses mainly on classes and objects.

Class : It is a group of objects with similar properties and behaviour. 

The term ' class' is used to define the class in C++. Basically, class is a template which defines the structure of the class. For example : car is a class that has a  state( Model, colour, engine, gear etc.)and behaviour (changing gear, speed, applying brakes etc.) 

Let us have a look at the first program in C++

#include<iostream.h>

void main()

{

    cout<<"\n HELLO";

}

Classes in programming : 

Keyword 'class ' is used to define a  class. 

It is used like a template of Abstract Data Type. 

It binds the data with the functions associated with it. 

It is like a blueprint of the data type.
