Summary
The 29th International Obfuscated C Code Contest (IOCCC) 2025 results are out, featuring deliberately confusing and creatively terrible C code entries. One standout entry this year surprisingly has a valid real-world use case, which is unusual for a contest that celebrates intentionally unreadable code. The judging concluded three weeks ago, with a three-hour YouTube recording of the results now edited into individual clips for each winner.
