# Sixth International Obfuscated C Code Contest 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. The Makefile for [Best self modifying program](fubar/index.html) always uses the most portable version because there is no loss of functionality in using it. In the case of the [Best game](tromp/index.html) entry, however, some functionality is lost in the portable version and so its Makefile uses the original program. This year, the [Best of Show](jar.2/index.html) was given to the most useful program. The [Strangest abuse of the rules](jar.1/index.html) award was given this year to stress the fact that starting in 1990, compiling entries must result a regular executable file. [Rules](rules.txt) and [results](../years.html#1989) were posted to _comp.lang.c_, _comp.sources.unix_ and _alt.sources_. They have been made available on a wide number of USENET archive sites such as _uunet_. The 1989 winning entries will be published in the [Micro/Systems Journal](https://www.vintage-computer.com/publications.php?microsystemsjournal). ## Final Comments **IMPORTANT NOTE**: See [contact.html](../contact.html) for up to date contact details as well as details on how to provide fixes to any of the entries.
