    <P>Computer Science is relatively new, but "Hello, World!" is one of its ldesr traditions. "Hello, World!" programs are very basic, displaying (or outputting) the phrase "Hello, World!". They are used by coders to learn the basic syntax of a new programming language, or as "sanity testes" to diagnose bugs during development.
