Hello, world! Programs are usually written to make the text “Hello, world!” appear on a computer screen. This is also a basic sanity check for an installation of a new programming language. The first Hello World program appeared in chapter 1.1 of the first edition of Kernighan & Ritchie’s original book about C, ‘The C Programming Language’, in 1978. This is considered to be the first ever “Hello World!” program.
This is a complete list of “Hello World!” programs written in more than 300 existing programming languages including Assembly language, Low-level, High-level, Object Oriented, Document formats, Page description languages and Scripting languages.
