Critical Code

A "Hello, World!" program is a computer program that outputs or displays "Hello, World!" to a user. Being a very simple program in most programming languages, it is often used to illustrate the basic syntax of a programming language for a working program.[1] It is often the very first program people write when they are new to a language.
