我见过的最疯狂的C代码

        Quora 原文：What are some of the most amazing C programs?

        C 语言是最强大的语言之一。但是到底它的强大表现在何处？写操作系统？Too young to naive!

        Quora 上众多程序员分享了自己见过的最令人惊叹的C语言代码。敲代码敲累了？看一些养眼的代码休息一下吧！

        1. 如何优雅地写一封信

        下面是 Brian Westley aka Merlyn LeRoy 写的一段C程序。但如果细读起来你会发现它是 Charlie 和 Charlotte 两人之间的书信！

        注：这段代码还能编译运行！

char*lie;  double time, me= !0XFACE,   not; int rested, get, out;  main (ly, die) char ly, **die ;{  signed char lotte,     dear; (char) lotte--;  for(get= !me;; not){  1s - out & out ;lie;{  char lotte, my= dear,  **let= !!me *!not+ ++die;  (char*)(lie= "The gloves are OFF this time, I detest you, snot\n\0sed GEEK!");  do {not= *lie++ & 0xF00L* !me;  #define love (char*) lie -  love 1s *!(not= atoi (let  [get -me?  (char) lotte-  (char) lotte: my- *love - 'I' - *love - 'U' - 'I' - (long) - 4 - 'U' ])- !!  (time =out= 'a'));} while( my - dear  && 'I'-1l -get- 'a'); break;}}  (char)*lie++;   (char)*lie++, (char)*lie++; hell:0, (char)*lie;  get *out* (short) ly -0-'R'- get- 'a'^rested;  do {auto*eroticism,  that; puts (*( out - 'c' -('P'-'S') +die+ -2 ));}while(!"you're at it");  for (*((char*)&lotte)^=  (char) lotte; (love ly) [(char)++lotte+ !!0xBABE];){ if ('I' -lie[ 2 + (char) lotte]){ 'I'-1l ***die; }  else{ if ('I' * get *out* ('I'-1l **die[ 2 ])) *((char*)&lotte) -= '4' - ('I'-1l); not; for(get=! get; !out;   (char)*lie & 0xD0- !not) return!!  (char) lotte;}     (char) lotte;    do{ not* putchar (lie [out *!not* !!me + (char) lotte]);     not; for(;!'a';);}while(  love (char*) lie);{      register this; switch( (char) lie     [(char) lotte] -1s *!out) {  char*les, get= 0xFF, my; case' ':    *((char*)&lotte) += 15; !not + (char)*lie*'s';  this +1s+ not; default: 0xF + (char*) lie;}}}   get - !out;     if (not--)  goto hell;     exit ( (char) lotte);}

        2. 分分钟画一幅地图

        这一小段貌不惊人的代码竟然能画出印度地图！！

  main ()  {  int a,b,c;  int count = 1;     for (b = c = 10;  a = "- FIGURE?, UMKC,XYZHello Folks,\ TFy!QJu ROo TNn (ROo) SLq SLq ULo+\  UHs UJq TNn*RPn/QPbEWS_JSWQAIJO^\  NBELPeHBFHT}TnALVlBLOFAkHFOuFETp\  HCStHAUFAgcEAelclcn^r^r\\tZvYxXy\  T|S~Pn SPm SOn TNn ULo0ULo#ULo-W\  Hq!WFs XDt!"[b+++21]; ) for(; a-- > 64 ; )  putchar ( ++c=='Z' ? c = c/ 9:33^b&1);     return 0;  }

        3. 自己输出自己的代码

 main () {      char q=34,      n=10,*a="main () { char q=34,          n=10,          *a=%c%s%c;          printf (a,q,a,q,n);      }%c";       printf (a,q,a,q,n);  }

        看着这段代码，想起了Tupper 自我指涉公式…

        One More Thing

        国际上还有个专门的比赛 IOCCC-The International Obfuscated C Code Contest，评选那些最奇怪最疯狂最有创意的C语言代码，到去年已经举办 22 届了。这些代码有的是图画，有的输出一些奇怪的东西，当然，它们都能完美地运行！

        程序员玩起来创意，是谁也比不过的！
