We add the following level-3 header to help people identify text they may wish to skip if they wish for a greater challenge: ``` ``` After that notice we add: ``` **If you want a greater challenge, don't read any further**: just try to understand the program via the source. If you get stuck, come back and read below for additional hints and information. ``` And sometimes follow with: ``` ``` Or sometimes follow with: ``` ``` Where the alt code impacts a "greater challenge", we add instead: ``` **If you want a greater challenge, don't read any further**: just try to understand the program without looking at the Alternate code. If you get stuck, come back and look at the Alternate code. ``` And where a given command impacts a "greater challenge", we add instead: ``` **If you want a greater challenge, don't read any further**: just try to understand the program without running the command below. If you get stuck, come back and run the following command: ``` Perform `make www` to perform the above and test under macOS.
Twentieth 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 it 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 (this
year we included most of the information by the submitters).
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.
The IOCCC has a website and now has a number of international mirrors. The primary website can be found at www.ioccc.org.
Remarks on some of the entries
There were some outstanding entries that did not win. Unfortunately some very good entries lost because they:
-
did not follow the "one program - one file" rule;
-
depended too much on 32 bit architectures;
-
were more of the "obfuscated math" kind rather than the "obfuscated C" kind.
We hope the authors of some of those entries will fix and re-submit them for the next IOCCC.
We believe you will be impressed with this year's winning entries. The Best of Show - Most Shrinkable is a fine example of character stitching. But don't ignore the other entries! There are games, puzzle solvers, utilities, eye candy, calculators and graphical and audio tools.
This year all authors are different, and there is a authors from a new country - China! Many authors won for the first time. (Please note that judging is done completely anonymously. Be warned that we may disqualify entries that reveal the identity of the submitter).
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.
