"Hello, World!" program

The "hello, world!" program is a very simple computer program that just tells the computer to display the message "hello, world!" on the screen.

It's like when you first meet someone and you say "hello" to them. This program is the computer's way of saying "hello" to the programmer who wrote it.

Just like you learn to say "hello" first when you're learning a new language, programmers usually learn to create the "hello, world!" program first when they're learning a new programming language.

It's a way to learn the basics of how to write and run code, and it's fun to see the computer do something in response to your command.
