Looking for a pocket compiler? CodeToGo could be the answer

CodeToGo has long been regarded as something of a 'novelty' mobile compiler for iOS devices mainly thanks to an inability to load or save code snippets. All that has changed with the latest version which enables the import and export of files using Dropbox, as well as the current code for whatever given language you are working in being automatically saved for you. What you end up with, for just a couple of bucks, is a handy mobile compiler and debugging tool which wraps around the Ideone.com service (so requires an Internet connection to run your code) and enables you to have a bit of fun in 50 different programming languages on your iPhone or iPad.
