International Obfuscated C Code Contest

International Obfuscated C Code Contest (IOCCC) is a computer programming contest in which contestants write short computer programs (usually less than 256 characters) that do interesting things but the code is intentionally written in a confusing and complicated way. The idea is to make a small program that is hard to understand. Contestants can win awards and prizes for writing the most creative, difficult to understand, or shortest code.
