  • obfuscated c contest — (programming)   The International Obfuscated C Code Contest (IOCCC) is an annual contest run since 1984 over Usenet by Landon Curt Noll and friends.

C's terse syntax and macro-preprocessor facilities give contestants a lot of maneuvering room. The winning programs often manage to be simultaneously funny, breathtaking works of art and horrible examples of how *not* to code in C.
