Prepare for the winners of **IOCCC28**. > However these are not the 2024 droids you are looking for. :-) The HTML menu (both JavaScript and non-JavaScript) has been updated. The `Status -> Rules and guidelines' have been replaced with two separate menus `Status -> IOCCC rules` and `Status -> IOCCC guidelines`. Added a new top level `social.html` page: built from a new `social.md`. Sorted rules for building specific web pages in the top level `Makefile`. Added `make social` to make the `social.html` page from `social.md`. The `bin/gen-top-html.sh` now is able to process a argument of **social** to process the new top level `social.html` page. Changed `bin/gen-top-html.sh` VERSION from "2.0.0 2025-03-13" to "2.0.1 2025-07-25". Below `About -> Home page` a new `About -> IOCCC social media` menu item as added. Because the menu change touched every HTML file, we changed the general copyright date range for HTML files from "1984-2024" to "1984-2025" due to the extensive changes made for **IOCCC28**. Those markdown files that were modified in 2025 had their copyright date range also changed from "1984-2024" to "1984-2025". Rebuilt tarballs and sitemap due to the extensive HTML rebuilding. Ran `make update` to perform the above.
Seventeenth International Obfuscated C Code Contest
Standard IOCCC stuff
View the index.html web page for the given winning entry for information on how
on how to compile the entry and how to run the winning program.
Look at the winning source and try to figure how it does what it does!
You may then wish to look at the Author's remarks for even more details.
Some ANSI C compilers are not quite as good as they should be. If
yours is lacking, you may need to compile using gcc instead of your
local compiler.
Historical note:
The IOCCC has a website and now has a number of international mirrors. The primary website can be found at www.ioccc.org.
Historical update:
The IOCCC website once had a number of international mirrors. As of 2020 Dec 29, GitHub serves as the distributed server farm for the IOCCC winner repo that GitHub renders as Official IOCCC website - www.ioccc.org.
Remarks on some of the entries
We believe you will be impressed with this year's winning entries. The Best of Show is a fine example of obfuscation. But don't ignore the other entries! There are games, utilities, programs that output images and a one-liner that is incredibly compact for what it can do.
The Best abuse of the guidelines is technically allowed by the rules. This year we allowed it due to the functionality of the program. This entry is one of the easiest to read! Don't assume you can win using similar techniques next time ... :-)
This year a single person won two awards! We also had repeat authors with their 6th, 4th and 2nd winning entries this year! (Please note that judging is done completely anonymously. Be warned that we may disqualify entries that reveal the identity of the submitter.)
Remarks on some losing entries
There were some outstanding entries that did not win. Unfortunately some very good entries lost because they:
- depended too much on non-portable side effects in expressions; and/or
- depended too much on a particular byte order; and/or
- required the use of a special script, data file or pseudo-machine language that was not supplied with the entry.
We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.
Final Comments
IMPORTANT NOTE: See contact.html for up to date contact details as well as details on how to provide fixes to any of the entries. See also the IOCCC FAQ for additional information on the IOCCC.
