Hello world c++

#include <iostream>

int main() {
    // Step 1: Include the necessary header file for input and output operations
    // The iostream header file provides functionality for input and output operations using streams, such as cin and cout.

    // Step 2: Define the main function
    // The main function is the entry point of a C++ program where the execution begins.

    // Step 3: Output "Hello, World!" to the console
    // The std::cout is the standard output stream used to display information on the console.
    // The << operator is used to send the "Hello, World!" string to the cout stream.

    std::cout << "Hello, World!" << std::endl;

    // Step 4: Return 0 to indicate successful execution
    // The main function typically returns an integer value to the operating system, where 0 usually indicates successful execution.

    return 0;
