Thank you for mentioning this! As idiomatic as the original loop might be it still forces someone unfamiliar with C to think about it carefully, on the other side this version is trivial to read and understand. Code should be always designed with readability in mind as we spend much of our time reading and understanding code (if an idiom makes hard to understand something I would probably consider it a bad idiom and avoid the style). EDIT: And no, there is also people that write code like you did regardless the language ;)
