The International Obfuscated C Code Contest

1990/stig - Strangest abuse of the rules

nested-comment tester (all on command line)

Author:

To build:

    make all

To use:

    make all

NOTE: that’s not a typo or mistake but one can also do:

    ./o

Judges’ remarks:

We changed the alias that the author’s suggested alias from a C-shell alias to a Bourne-like shell alias.

Note that shst.c is renamed to stig.c in the distribution.

WARNING: This program’s how to compile is too specific to a particular shell. The obfuscation of this program is more related to shell obfuscation than C obfuscation. This type of entry will not be permitted in future contests.

Author’s remarks:

If you like shell programming you may also admire my creative quoting. (I use echo to create an alias which when run calls cc with the -D option to create a C macro with double quotes in it. ARRRRRGGGHHH!)

The program is totally portable, but the compile commands are very shell specific so don’t be TOO mad at me if they don’t work for you.

If you want to put these commands in a Makefile you must add 4 - four - backslashes at the end on first line. (At least that’s what works here.)

If everything works correctly it create an executable named o which checks whether your compiler supports nested comments. I’ve stolen the "/*/*/0*/**/1" from somewhere so don’t give me any points for it. Of course neither ANSI nor K&R support nested comments when properly implemented, but what the heck.
