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 variablesnum1
andnum2
are declared to store the input integers.std::cout << "Enter the first integer: ";
: This line uses thecout
(console output) stream to display a message prompting the user to enter the first integer.std::cin >> num1;
: Thecin
(console input) stream is used to read the first integer entered by the user and store it in the variablenum1
.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 variablesum
.std::cout << "The sum of " << num1 << " and " << num2 << " is " << sum << std::endl;
: This line usescout
to display the result, including the values ofnum1
,num2
, andsum
.return 0;
: This line indicates that the program has executed successfully and is returning a status code of0
to the operating system.
This program provides a clear demonstration of how to read input, perform calculations, and display output using C++.
