What is C++ Language ? Calculate sum of two numbers in C++ Language

Introduction: C++ (pronounced  “ see plus plus”) is a general purpose programming language developed by “Bjarne Stroustrup” as an extension to 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

C++ is one of the most popular programming languages that runs on variety of platforms like Windows, UNIX, Mac OS etc

• 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=45

Enter second number=55

Sum of 45 and 55 = 100
