(foldoc) | Obfuscated C Contest
The International Obfuscated C Code Contest
(IOCCC) is an annual contest run since 1984 over Usenet by
Landon Curt Noll and friends. The overall winner is whoever
produces the most unreadable, creative, and bizarre (but
working) C program. Various other prizes are awarded at the
judges' whim. C's terse syntax and macro-preprocessor
facilities give contestants a lot of maneuvering room. The
winning programs often manage to be simultaneously funny,
breathtaking works of art and horrible examples of how *not*
to code in C.
This relatively short and sweet hello, world program
demonstrates obfuscated C:
/* HELLO WORLD program
* by Jack Applin and Robert Heckendorn, 1985 */
main(v,c)char**c;{for(v[c++]="Hello, world!\n)";
(!!c)[*c]&&(v--||--c&&execlp(*c,*c,c[!!c]+!!c,!c));
**c=!c)write(!!*c,*c,!!**c);}
Here's another good one:
/* Program to compute an approximation of pi
* by Brian Westley, 1988 */
#define _ -F |

n.
(in full, the ‘International Obfuscated C Code Contest’, or IOCCC) An
annual contest run since 1984 over Usenet by Landon Curt Noll and friends.
The overall winner is whoever produces the most unreadable, creative, and
bizarre (but working) C program; various other prizes are awarded at the
judges' whim. C's terse syntax and macro-preprocessor facilities give
contestants a lot of maneuvering room. The winning programs often manage to
be simultaneously (a) funny, (b) breathtaking works of art, and (c)
horrible examples of how not to code in C.
This relatively short and sweet entry might help convey the flavor of
obfuscated C:
/*
* HELLO WORLD program
* by Jack Applin and Robert Heckendorn, 1985
* (Note: depends on being able to modify elements of argv[],
* which is not guaranteed by ANSI and often not possible.)
*/
main(v,c)char**c;{for(v[c++]="Hello, world!\n)";
(!!c)[*c]&&(v--||--c&&execlp(*c,*c,c[!!c]+!!c,!c));
**c=!c)write(!!*c,*c,!!**c);}
Here's another good one:
/*
* Program to compute an approximation of pi
* by Brian Westley, 1988
* (requires pcc macro concatenation; try gcc -traditional-cpp)
*/
