Quick testing of code online

Hi there, happy holidays everyone! A really quick post with a helpful link, if you need to test a small code idea quickly online. The website: http://www.ideone.com will run multiple languages, and even lets you input data using standard in and out. Codepad (http://codepad.org/) is another popular one, but it doesn’t support standard in/out. As usual feel free to comment with more suggestions!
