What is Hello world: Definition and 14 Discussions

A "Hello, World!" program generally is a computer program that outputs or displays the message "Hello, World!". Such a program is very simple in most programming languages, and is often used to illustrate the basic syntax of a programming language. It is often the first program written by people learning to code. It can also be used as a sanity test to make sure that a computer language is correctly installed, and that the operator understands how to use it.

    How do you do, fellow kids

    I'm currently doing some post-grad research into open quantum systems in the UK. I've got a strong background in particle physics, theoretical physics and a load of other things that involve wibbly-wobbly timey-wimey physical phenomena. Anyways, I hope you're all having a wonderful weekend!
