c++ code

Sure! Here is an example of C++ code with explanations for each step:

#include <iostream>

int main() {
    // Step 1: Declare variables
    int num1, num2, sum;

    // Step 2: Read input from user
    std::cout << "Enter two numbers: ";
    std::cin >> num1 >> num2;

    // Step 3: Perform addition
    sum = num1 + num2;

    // Step 4: Display the result
    std::cout << "The sum is: " << sum;

    // Step 5: End the program
    return 0;
}

Step 1: Declare variables

In this step, we declare three variables: num1, num2, and sum. These variables will be used to store the numbers entered by the user and the result of the addition.

Step 2: Read input from user

Here, we use the std::cin object to read input from the user. The std::cout object is used to display the prompt message asking the user to enter two numbers. The >> operator is used to extract the input values and store them in the variables num1 and num2.

Step 3: Perform addition

In this step, we add the values of num1 and num2 and store the result in the variable sum using the + operator.

Step 4: Display the result

Here, we use the std::cout object to display the result of the addition. The << operator is used to insert the value of sum into the output stream.

Step 5: End the program

Finally, we return 0 from the main function to indicate successful execution of the program. This is a convention in C++ to indicate that the program has completed without any errors.
