C++ Program to Add Two Numbers

Example: Program to Add Two Numbers

#include <iostream>
using namespace std;

int main()
{
    int firstNumber, secondNumber, sumOfTwoNumbers;
    
    cout << "Enter two integers: ";
    cin >> firstNumber >> secondNumber;

    // sum of two numbers in stored in variable sumOfTwoNumbers
    sumOfTwoNumbers = firstNumber + secondNumber;

    // Prints sum 
    cout << firstNumber << " + " <<  secondNumber << " = " << sumOfTwoNumbers;     

    return 0;
}

Output

Enter two integer: 2
2
2 + 2 = 4

Working of above Program

In this program, user is asked to enter two integers. These two integers are stored in variables firstNumber and secondNumber respectively.

Then, the variables firstNumber and secondNumber are added using + operator and stored in sumOfTwoNumbers variable. Finally, sumOfTwoNumbers is displayed on the screen.
