computer program that produces the message "Hello, world!", often used to illustrate the basic syntax of a programming language
A "Hello world" program is a simple computer program that displays the message "Hello, world!" on a screen. It's commonly used as a first exercise when learning to code because it demonstrates the basic building blocks and rules of a programming language in the most straightforward way possible.

A "Hello, world" program is usually a simple computer program that displays on the screen (often the console) a message similar to "Hello, world". A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax. Such a program is often the first written by a student of a new programming language, but it can also be used as a sanity check to ensure that the computer software intended to compile or run source code is correctly installed, and that its operator understands how to use it.
