Sometimes I need to compile and run a tiny snippet of C++ code. For example, I want to proof some concept or I want to give code example while chatting with friends. Sometimes I don’t have access to good compiler. If I’m logged to irc.freenode.net, it’s not a problem - geordi is there. I’ve just found a Web-based alternative - codepad.org. It is a pastebin service that can compile, validate and execute your code.
