The Hello World Collection

"Hello World" is the first program one usually writes when learning a new programming language. Having first been mentioned in Brian Kernighans tutorial to the B programming language, it became widely known through Kernighan & Ritchies 1978 book that introduced "The C Programming Language", where it read like this:

main() {
printf("hello, worldn");
}

Since then, Hello World has been implemented in just about every programming language on the planet. This collection includes 565 Hello World programs in as many more-or-less well known programming languages, plus 76 human languages.

The programs in this collection are intended to be as minimal as possible in the respective language. They are meant to demonstrate how to output Hello World as simply as possible, not to show off language features. For a collection of programs that tell more about what programming in the languages actually is like, have a look at the 99 Bottles of Beer collection.

The Hello World Collection, started in 1994, was compiled with help from many people around the world. It is the biggest collection of Hello World programs on the Internet, and the only one collecting human languages as well. To contribute, send your program to [email protected]. Begin your contribution with a comment in the respective language. Real programming languages only please.
