Let's explore the winning submissions of The International Obfuscated C Code contest! Held every year, the IOCCC is a celebration of the syntactical quirks and unique features of C, encouraging submitters to create the most unreadable and unique code possible.
In this video, you'll also learn how to quickly deobfuscate IOCCC submissions using various reverse-engineering tricks, turning the indecipherable syntax into something more human-understandable.

I'm a little sad she didn't mention the most coveted prize in the contest, "Best Abuse of the Rules", usually awarded when someone finds a way to so horrifically abuse the rules that they have to be changed going forward. In 1994, "smr" submitted the smallest self-reproducing program, a program that, when executed, outputs it's own source code. He achieved this by creating a source file, the only source file in the submission, which was 0 bytes long. Exactly 0 bytes. It was empty. However, due to clever abuse of the Makefile, the compiler still output an executable. An empty one. What did it do? Nothing. It just instantly exited. But it's output of absolutely nothing was technically all of his source code.

I rewrote it in Python in under 50 lines. Not only did it run about 10 times faster, it was actually comprehensible.

Just an old head looking to get into programming. Teach us young grasshopper!

@filker0 2 месяца назад

I used to enter the obfuscated C competition back in the 1980s. I never came close to winning, but I did my worst, which is all that can be reasonably expected. There are better tools for unubfusticating the contest entries. "indent", "astyle", and other source code reformatting utilities, "cpp" for doing macro expansion, "m4" and "awk" round out the toolkit. Around 1989-1990 I wrote a C code obfusticator and posted it to alt.sources. Unfortunately, it didn't handle ANSI C function prototypes and used semantic dirty tricks that are not portable across pre-ANSI compilers and in places conflict with ANSI additions to the C language grammar.
