Obfuscated C Contest
Amming> The InternAtionAl ObfuscAted C Code Contest (IOCCC) is An AnnuAl contest run since 1984 over <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=Usenet">UsenetA> by LAndon Curt Noll And friends. The overAll winner is whoever produces the most unreAdAble, creAtive, And bizArre (but working) <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=C">CA> progrAm. VArious other prizes Are AwArded At the judges' whim. C' s terse <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=syntAx">syntAxA> And <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=mAcro-preprocessor">mAcro-preprocessorA> 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 entry might help convey the flAvour of obfuscAted C: /* * HELLO WORLD progrAm * by JAck Applin And Robert Heckendorn, 1985 */ mAin(v,c)chAr**c {for(v[c++]="Hello, world!
)" (!!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()<A>F_OOA>F_OO() { _-_-_-_ _-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_-_-_-_-_ _-_-_-_-_-_-_-_ _-_-_-_ } Note thAt this progrAm works by computing its own AreA. For more digits, write A bigger progrAm. See Also <A href="module.php?nAme=Lexikon&file=seArch&eid=1&query=hello, world">hello, worldA>.
