Ideone is an online development platform that allows users to write, compile, debug and share code in various programming languages including Java, C++, PHP, Python, Ruby, and more. It is a great resource for those who are learning to code, as it allows them to experiment with code without having to install any software onto their computer. It also comes in handy for experienced developers who need to quickly test some code or debug an issue. Users can also share code snippets with others and even allow them to run and modify the code.
