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
To use:
./prog < input > output
Try:
./try.sh
Judges' remarks:
If you look closely at the source, you will see code that appears to puts C code that includes itself. How and why? Perhaps it is in the DNA code of the code? Perhaps there are 23 reasons? :-)
Author's remarks:
Remarks
This chromosome program synthesizes a double helix. The helix can also be compiled as a C program.
Enjoy DNA programming!
For more information / background reading:
-
This program was inspired by Acme::DoubleHelix: http://search.cpan.org/~xern/Acme-DoubleHelix-0.01/
-
The synthesized helix just includes the original program at the head. Do you see how prog.c determines whether it was invoked as a standalone program or included as a header file? Note that it does not use any gcc extension such as
__INCLUDE_LEVEL__. -
The synthesized helix of course follows the base-pairing rules for DNA: A is bonding only to T, and C is bonding only to G.
