Hello World

A "Hello, World!" program is a simple computer program that outputs or displays the message "Hello, World!" on the screen, typically in a console or terminal window. It is commonly used as the first program written by people learning a new programming language to illustrate the language's basic syntax and to verify that the programming environment is correctly set up.
