c++ adding program

Miles is learning C++. Please demontrate a simple program that adds two integers. Please make sure that the program has good comments so that he can understand it just by reading the code.

Absolutely, I'd be happy to provide you with a simple C++ program that adds two integers and includes comments for Miles to understand the code. Here's the program:

#include <iostream>  // Include the input/output stream library

int main() {
    // Declare variables to hold the two integers
    int num1, num2;

    // Prompt the user to enter the first integer
    std::cout << "Enter the first integer: ";
    std::cin >> num1;

    // Prompt the user to enter the second integer
    std::cout << "Enter the second integer: ";
    std::cin >> num2;

    // Calculate the sum of the two integers
    int sum = num1 + num2;

    // Display the result
    std::cout << "The sum of " << num1 << " and " << num2 << " is " << sum << std::endl;

    return 0;  // Indicate successful program execution

Explanation of the Code:

  • #include <iostream>: This line includes the input/output stream library, which provides functionality for reading from and writing to the standard input and output streams.

  • int main(): This is the main function where the program's execution starts.

  • int num1, num2;: Here, two integer variables num1 and num2 are declared to store the input integers.

  • std::cout << "Enter the first integer: ";: This line uses the cout (console output) stream to display a message prompting the user to enter the first integer.

  • std::cin >> num1;: The cin (console input) stream is used to read the first integer entered by the user and store it in the variable num1.

  • Similar steps are followed to read the second integer from the user.

  • int sum = num1 + num2;: The sum of the two integers is calculated and stored in the variable sum.

  • std::cout << "The sum of " << num1 << " and " << num2 << " is " << sum << std::endl;: This line uses cout to display the result, including the values of num1, num2, and sum.

  • return 0;: This line indicates that the program has executed successfully and is returning a status code of 0 to the operating system.

This program provides a clear demonstration of how to read input, perform calculations, and display output using C++.
