The "Hello, World!" program is often the first program beginners write when learning a new programming language. Its purpose is to demonstrate the basic structure of a C program and how to display output to the screen.

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

	int main() {

	printf("Hello, World!\n")  // Prints "Hello, World!" followed by a new line

	return 0;                  // Indicates successful program termination

}     

Explanation of the Code

1. #include

• This line includes the Standard Input/Output library (stdio.h) in the program.
• It provides the printf function, which is used to display output.

1. int main()

• This defines the main function, where the program starts execution.
• int indicates that the function returns an integer value.

1. printf("Hello, World!\n");

• printf is a function used to print text to the screen.
• "Hello, World!" is the text that will be displayed.
• \n is an escape sequence that moves the cursor to a new line after printing.

1. return 0;

• This statement indicates that the program has executed successfully.
• A 0 value is returned to the operating system.

Output

When you run the program, the output will appear as:

Hello, World!
