Define C++ Language? Calculate sum of two numbers in C++ Language

Introduction: 

C++ is an object oriented programming (OOP) language, developed by “Bjarne Stroustrup”, and is an extension of C language, starting in 1979 at Bells labs. C++ was originally named “C with Classes”, adding object oriented features, such as Objects, Classes, Abstraction, Encapsulations, Inheritance, Polymorphism, Overloading and other enhancements to the C programming language.  It was renamed to C++ in 1983.

Working Example of C++:

Now let’s create our first simple program to calculate the sum of two numbers in C++ Language 

#include<iostream.h>

#include<conio.h>

void main()

{

 clrscr();

 int a,b,sum;

 cout<<"Enter first number= ";

 cin>>a;

 cout<<"Enter second number= ";

 cin>>b;

 sum=a+b;

 cout<<"\nSum of " <<a<<" and "<<b<<" = "<<sum;

 getch();

}

Output:

Enter first number=10

Enter second number=15

Sum of 10 and 15 = 25
