What is Hello World
Hello World is a simple program that, when run, displays the message: Hello World . Fittingly, the Hello World program has long been the new programmer’s induction into a myriad of programming languages.
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. It is often the very first program people write when they are new to a language.
