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.
To build:
make all
To use:
./bas2 < file
echo text | ./bas2
Try:
./try.sh
./try.sh "foo bar" "baz" "IOCCC 1998/bas2" README.md
./try.sh try.sh "bas2.c" bas2.orig.c
Judges' remarks:
Questions to ponder:
Can you determine the relationship between the input and the resulting numeric output?
The program was not designed to process files with a certain octet value, what value is that?
Hint and Extra Credit:
This entry points out a minor flaw in the IOCCC rules that has been around since 1992. It processes a certain octet value in a way that differs from a strict reading of one of the official IOCCC rules. What is the rule and what is the octet value?
Author's remarks:
The main obfuscation is the way characters are recognized, which is done by matching the bit patterns. Minor obfuscations are:
-
Useless layout.
-
Useless variable names.
-
Recursive
main()instead of 2 loops (over input characters and over bits in the character). -
?:and||instead of if statements.
