Hello World

By on July 14, 2005

The Hello World Collection: Here’s a collection of the common “Hello World” progams written in 196 different programming languages. It looks pretty thorough to me, but if he missed any he’ll gladly take new contributions if you send them to him.

  1. Wikipedia has a good list too:

    They also explain the history of the tradition:

    […] the tradition of using the phrase “Hello world!” as the test message was influenced by an example program in the book The C Programming Language, by Brian Kernighan and Dennis Ritchie, published in 1978. The example program from that book prints “hello, world” (i.e., no capital letters, no exclamation sign; those entered the tradition later). The book had inherited the program from a 1974 Bell Laboratories internal memorandum by Kernighan —Programming in C: A Tutorial— which shows the first known version of the program.

    […] However, the first known instance of the usage of the words “hello” and “world” together in computer literature is in A Tutorial Introduction to the Language B, by Brian Kernighan, 1973.
