About Rosetta Code
Rosetta Code was started in 2007 by Michael Mol. The website's content is free to use and share under a special license called the GNU Free Documentation License. This means many people can use and learn from the code examples.
The site is a huge collection of code examples. It shows how to do the same task in many different programming languages. This helps you see how each language works and how they are similar or different.
As of September 25, 2019, Rosetta Code had:
- 971 computer problems to solve
- 225 extra problem ideas being worked on
- 723 different programming languages
- 66,679 examples of code in those languages
How Rosetta Code Works
The Rosetta Code website is set up so you can easily explore it. You can look for specific programming problems or for different programming languages.
Each problem has its own page. On this page, you can see solutions that people have shared in various programming languages. This makes it easy to compare how different languages solve the same problem.
Also, each programming language has its own page. This page lists all the problems that have solutions written in that language. For example, if a problem has a solution in the C language, it will be listed on the C language page. If the same problem also has a solution in Ruby, it will be on the Ruby page too.
