第 25 届国际 C 语言混乱代码大赛日前已成功举办，并公布获奖作品名单和代码。国际 C 语言混乱代码大赛（IOCCC, The International Obfuscated C Code Contest）是一项国际编程赛事，目的是写出最有创意的最让人难以理解的 C 语言代码，并限制在 4 kilobytes 以内。
之前常在该比赛中拿奖的浙大教授侯启明和 Google 的 Don Yang 再次获奖。侯启明这次写了一个 JSON 转 SVG 饼状图的转换器，这也是他第五次获奖。Don Yang 则是第 8 次拿奖，写的是一个文本翻转和移位器（Text rotator and shifter）。
此外，著名开源项目 FFmpeg 和 QEMU 的作者 Fabrice Bellard 也参加了比赛并获奖，他的作品是一个图像压缩 demo 。
获奖名单一览：
一些有意思的代码如下：
