Tic-Tac-Toe Implemented in Single Call to printf()

Tic-Tac-Toe Implemented In Single Call To Printf():

[Nicholas Carlini] programmed a C implementation of two-player Tic Tac Toe, and he did it in a single call to printf(). The arguments for that single function call get mind-bendingly complex, so it may come as no surprise that it was written for The International Obfuscated C Code Contest (IOCCC).

Most of us are aware that printf() is one of those functions that is considerably more complex under the hood, and capable of far more, than it may appear to be. But did you know that it is capable of Turing-complete computation?

Can't wait to see the version that can play checkers and chess!

    These guys would have a field day with APL.

    Back then, there used to be all sorts of one-line code porn, like this one line of APL code that could draw an elephant.

    So a single line of APL could generate all of systemd as its output? Wow.
