#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}

1. The #include <iostream> statement includes the input/output stream library, allowing the program to perform input and output operations.

2. The int main() function is the entry point of the program, where the execution begins.

3. Within the main() function, std::cout is used to print the "Hello, World!" message to the standard output.

4. The << operator is used to insert the message into the output stream.

5. std::endl is used to insert a new line character and flush the stream.

6. Finally, return 0; is used to indicate successful termination of the program.
