The International Obfuscated C Code Contest
The International Obfuscated C Code Contest (abbr. IOCCC) is a
programming contest for the most creatively obfuscated C code
held annually since 1984 (with the exception of 1997, 1999, and 2002).
There are many winning entries each year, and each entry gets a category like
"Worst Abuse of the C Preprocessor" or "Most Erratic Behavior".
One notable IOCCC winner (in 1986 and 1987) is Larry Wall.
His achievements in IOCCC may or may not be related to his design of Perl.
