Here's the updated code with comments and explanations:

#include <stdio.h>  // Includes the standard input-output library for input-output functions

int main() {  // Main function where the program execution starts
    // Prints "Hello, World!" followed by a newline character to the console
    printf("Hello, World!\n");  // %s is not required here because it's a direct string literal

    return 0;  // Returns 0, indicating successful program execution
}

Explanation:

• #include <stdio.h>: This line includes the standard input-output library, which is required to use functions like printf in the program.
• int main(): The main function is the entry point of the program, where execution begins.
• printf("Hello, World!\n");: The printf function is used to print the string "Hello, World!" to the console. The \n at the end ensures that the cursor moves to the next line after printing.
• return 0;: This line indicates that the program has finished successfully and returns 0 to the operating system.

This is a classic "Hello, World!" program, often used as a first example when learning a programming language. It demonstrates the basic syntax of C, including how to print output to the console.
