It should be pointed out that there are a few inconsistencies as noted below. In some years the title of entries that were explicitly listed were linked to but as the README.md files no longer have the title it was not as easy to locate the title (I could go back in archive/historic and I did in some cases but I was trying to hurry this up to close #3). It's most likely that some have backticks surrounding certain words like gcc or something else but not in all files. An example that might be there is '#define'. Some wording is different. Usually this is due to the original wording which I did not think was good to change. There might be other cases that were missed as well. One thing is that comes to mind is that in some README.md files it refers to the Makefile to check for build instructions, in others it refers to the index.html file and in some it refers to both. But the index.html has how to build so they should probably all say index.html and not refer to the Makefile. This was also done in a rush. There might be other inconsistencies or things that might want to be fixed but whether it's worth it given is unclear at this time. It can be argued that the reference to the Makefiles for build instructions is a historical comment to keep there as an example of why not to change it. There were other things I noticed that I could not address or did not feel were necessary but with this commit an important task is can likely be considered done unless it is decided that some of these should be fixed or if looking at the rendered output there is a problem.
Fourth International Obfuscated C Code Contest
View the index.html web page for the given winning entry for information on how
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.
The rules for 1997 suggested even more categories than in 1986.
Hints for what to do and not to do were also given in the rules.
For example, a simple excessive abuse of /lib/cpp was discouraged unless the
abuse was unusual. The mailboxes for the contest were moved from nsc to amdahl.
The practice of posting a preliminary set of rules for the next year was started
this year.
Rules and results were posted to comp.lang.c and comp.unix.wizards
with an announcement in news.announce.important.
Micro/Systems Journal
published the 1987 winning entries. Mark R.
Horton included
a version of the 1987 winning entries in an appendix of his C book
Portable C Software International
Edition.
The first announcement of winning entries at the Summer 87 USENIX was helped by a small
fly that danced all over the foils.
