c++code

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

#include <iostream>

int main() {
    int num1, num2, sum;

    // Prompt the user to enter two numbers
    std::cout << "Enter two numbers: ";

    // Read the input from the user
    std::cin >> num1 >> num2;

    // Calculate the sum of the numbers
    sum = num1 + num2;

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

    return 0;
}

Explanation:

• Line 1: The #include <iostream> directive is used to include the necessary header file for input/output operations in C++.

• Line 3: The int main() function is the entry point of the program. It is where the execution of the program begins.

• Line 5: Three variables num1, num2, and sum are declared to store two numbers and their sum.

• Line 8: The std::cout statement is used to display the prompt message asking the user to enter two numbers.

• Line 11: The std::cin statement is used to read the input from the user. It reads two numbers entered by the user and assigns them to num1 and num2 variables.

• Line 14: The sum of num1 and num2 is calculated and stored in the sum variable.

• Line 17: The std::cout statement is used to display the result, which shows the sum of the two numbers.

• Line 19: The return 0; statement is used to indicate that the program has successfully executed and is returning a value of 0 to the operating system.

This code prompts the user to enter two numbers, calculates their sum, and displays the result.
