#12Freek Wiedijk's Most Functional winner of the 2014 International Obfuscated C Code Contest is an obvious candidate.:

I never thought code could make me feel like this.

Ever waste days debugging a subtle bug introduced by C macros? It's PTSD material.
I love C but I will never understand why C has a naive macro system.

#15Beautiful code is simple maintainable code. In C this is a simple as: #include int main(void) { puts("42"); return 0; }
I was curious why you would return a value and not just make the main function return void (in the interests of simplicity and maintainability, and assuming you're using C not C++). So I wrote my own such program, and discovered that void main(void) returns 3 to the OS. Any ideas why?

Could be "improved"
#define SIX 1+8
#define NINE 5+1Re: The Most Beautiful Piece of Code That Prints 42

Because returning void means that, on most platform, return whatever is left in %eax at the time of function termination.

Nice.

I always thought it was a historical choice that simple substitution languages were simpler to implement so were chosen as a default.
It is kind of infuriating that the preprocessor always feels simultaneously _too powerful_ and _not powerful enough_ for the jobs you want to get done. I find myself reaching for other tools (kaitai, m4 etc) a lot more these days to take the role.

#20Like most code, this is way too easy in Perl 6. > perl6 -e 'say "Life, the Universe and Everything".WHY' 42
For non perl users - does this really work or are you being ironic?
