I publicly reverse-engineered a cute bit of C code many years ago that employs some of these tricks: https://stackoverflow.com/questions/15393441/obfuscated-c-code-contest-2006-please-explain-sykes2-c https://stackoverflow.com/questions/15393441/obfuscated-c-co... It's a digital clock (which has to be compiled and run once per second to be accurate). Of course, if you're interested in obfuscated C, you can't miss the International Obfuscated C Code Contest, which is where most of these evil tricks show up. Submissions for this year's IOCCC are still open: https://www.ioccc.org/ https://www.ioccc.org/ The IOCCC has been running since 1984, and there are some absolutely marvelous gems: https://www.ioccc.org/years.html https://www.ioccc.org/years.html. A great rabbit-hole to dive down if you're stuck at home ;)
