Add Two Numbers from Keyboard

Write a C++ program to add two numbers and accept them from the keyboard.

Visual Presentation:

Sample Solution:

C++ Code :

#include <iostream> // Including the input-output stream header file

using namespace std; // Using the standard namespace

int main() // Start of the main function
{
	int num1, num2, sum; // Declaring integer variables num1, num2, and sum

    cout << "\n Sum of two numbers :\n"; // Outputting a message indicating sum of two numbers
	cout << "-------------------------\n"; // Outputting a separator line   

    cout << " Input 1st number : "; // Prompting the user to input the first number
	cin >> num1 ; // Taking input for the first number from the user

	cout << " Input 2nd number : "; // Prompting the user to input the second number
	cin >> num2; // Taking input for the second number from the user

	sum = num1 + num2; // Calculating the sum of the two numbers

	cout <<" The sum of the numbers is : " << sum << endl; // Displaying the sum of the numbers
	cout << endl; // Outputting a blank line for better readability

	return 0; // Returning 0 to indicate successful program execution
} // End of the main function

Sample Output:

 Sum of two numbers :                                                  
-------------------------                                              
 Input 1st number : 25                                                 
 Input 2nd number : 39                                                 
 The sum of the numbers is : 64
