    Obfuscated C Contest


    n. 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 */ 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<00||--F-OO--; int F=00,OO=00; main()F_OO();printf("%1.3f\n",4.*-F/OO/OO);F_OO() { _-_-_-_ _-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_ _-_-_-_ }
