In the very early days of C, the compiler written by Dennis Ritchie and supplied with the UNIX operating system entirely defined the language. As the number of users and C implementations grew, however, so too did the need for a language standard-a contract between users and implementers about what should and should not count as C. This effort began in 1983 with the formation of a committee tasked with producing "an unambiguous and machine-independent definition of the language C" and led to the ANSI C Standard in 1989.1 In retrospect, it was not until this date, 17 years after the first compiler, when C's most notorious language feature slithered into the world: undefined behavior.
