{{mp_explore}}
Rosetta Code is a repository for code examples that go beyond the traditional "Hello World!" example. A series of tasks are listed, and visitors to this site are asked to complete the tasks in the language of their choice. The tasks are intended to cover a variety of needs commonly found in software.
{{mp_contribute}}

You may browse the site any of the following ways...

* ...by [[:Category:Compilers and Interpreters|compilers or interpreters]] used,
* ...by [[:Category:Programming Tasks|programming tasks]] solved.

Feel free to request that things be added, too:

* [[Help:Request a new programming language|Request a programming language]].
* [[Help:Request a new programming task|Request a programming task]].

===New!===

The browsing structure will be changing soon. Try out our new [[:Category:Solutions|Solutions category]], where you can easily find where each programming language or library was used.

==News and Updates==
Please visit the [http://blog.rosettacode.org Rosetta Code Blog], where news and updates may be found.

Rosetta Code is a programming chrestomathy site. The idea is to present solutions to the same task in as many different languages as possible, to demonstrate how languages are similar and different, and to aid a person with a grounding in one approach to a problem in learning another. Rosetta Code currently has 1,272 tasks, 403 draft tasks, and is aware of 944 languages, though we do not (and cannot) have solutions to every task in every language.
