Adding Two Integer in C++

 

The next level of programming in C++. Adding the two integer.

Below is a simple program in adding two integers:

#include<iostream>                      /* header */



int main ()

{

int number1;                                              /* declaration */

std::cout << "Enter first integer: ";                 /* prompt */
std::cin >> number1;                            /* read the first integer */

int number2, sum;                               /* declaration */

std::cout << "Enter second Integer: ";            /* second prompt */
std::cin >> number2;                          /* read the second integer */

sum = number1 + number2; /* adding two integer input */

std::cout << "Sum = " << sum << std::endl; /* print the sum */

return 0;

}




You can see that without declaring the std you will need to enter it in your statement.

std::cin >> - it is also means scanf in C.
