primes-cpp VS ioccc-obfuscated-c-contest

Everybody mentions this, and what's great is that it is a pretty natural solution to a lot of problems. I remember coming up with a version of it while writing an optimized prime-sieve[1], and was surprised when I later learned that it was some named technique.

In addition to just the basic loop-unrolling (which I'm pretty sure you usually don't need to do by hand with modern compilers), it works really well when you need to jump into the middle of a pattern. Like if you're sieving primes in a wheel-factorized array.

  // Here we're only checking possible primes after wheel-factorization

A semi-automated system that compares old unsafe code to new unsafe code would likely be really helpful here - say, a LLM prompted to investigate whether the new unsafe blocks are a significant difference in scope and documented intent from the old unsafe blocks. Unless the winners of https://www.ioccc.org/ are among your attackers, it's a pretty solid line of defense.

For that you can go savor the archives of IOCCC : https://www.ioccc.org/

>> Perl can also be hilariously unreadable: https://www.foo.be/docs/tpj/issues/vol4_3/tpj0403-0017.html

Most programming languages can be obfuscated. That does not mean people write code in those programming languages like that:

C: https://www.ioccc.org/

Javascript: view-source:https://www.google.com/

The truth is that insulting Perl is considered stylish by some, so many people do despite knowing little to nothing about Perl and having never used it.

If you want the most complex, then probably here https://www.ioccc.org/

Since someone already linked Enterprise FizzBuzz, I'll link The Obfuscated C Contest as a possible source of inspiration.

Or this one [3] that calculates pi by estimating its own surface area.

Or this one [4]. It's a lovers quarrel, written simultaneously in C and English. It's incredible, seriously, read it.

I wonder what sort of "English" it spits out when fed obfuscated C code

OP is going to rage quit when he sees https://www.ioccc.org/

I mean, its no https://www.ioccc.org/ entry
