Have you ever come across a code snippet you really wanted to try out but you weren’t near a compiler? Believe it or not, that happens to me sometimes. It turns out there is a pretty neat free web-based compiler out there called ideone (i.e. Integrated Development Environment One). It lets you paste code (supports 40 programming languages!) into the browser window, compiles and runs it, and gives you the output. It even syntax highlights it for you.
So it’s a great tool for getting your feet wet in a new language or trying out a code fragment and printf’ing its output. Basically it’s a fun place to hack in a sandbox. I like to use it as a lightweight testing environment during prototyping. Check it out, I figured I’d share the love :).
