下面的六個程序片段主要完成這些事情：

輸出Hello, World
混亂C語言的源代碼
下面的所有程序都可以在GCC下編譯通過，只有最后一個需要動用C++的編譯器g++才能編程通過。

hello1.c

  #define _________ }  #define ________ putchar  #define _______ main  #define _(a) ________(a);  #define ______ _______(){  #define __ ______ _(0x48)_(0x65)_(0x6C)_(0x6C)  #define ___ _(0x6F)_(0x2C)_(0x20)_(0x77)_(0x6F)  #define ____ _(0x72)_(0x6C)_(0x64)_(0x21)  #define _____ __ ___ ____ _________  #include<stdio.h>  _____

hello2.c

  #include<stdio.h>  main(){   int x=0,y[14],*z=&y;*(z++)=0x48;*(z++)=y[x++]+0x1D;   *(z++)=y[x++]+0x07;*(z++)=y[x++]+0x00;*(z++)=y[x++]+0x03;   *(z++)=y[x++]-0x43;*(z++)=y[x++]-0x0C;*(z++)=y[x++]+0x57;   *(z++)=y[x++]-0x08;*(z++)=y[x++]+0x03;*(z++)=y[x++]-0x06;   *(z++)=y[x++]-0x08;*(z++)=y[x++]-0x43;*(z++)=y[x]-0x21;   x=*(--z);while(y[x]!=NULL)putchar(y[x++]);  }

hello3.c

  #include<stdio.h>  #define __(a) goto a;  #define ___(a) putchar(a);  #define _(a,b) ___(a) __(b);  main()  { _:__(t)a:_('r',g)b:_('$',p)   c:_('l',f)d:_(' ',s)e:_('a',s)   f:_('o',q)g:_('l',h)h:_('d',n)   i:_('e',w)j:_('e',x)k:_('/n',z)   l:_('H',l)m:_('X',i)n:_('!',k)   o:_('z',q)p:_('q',b)q:_(',',d)   r:_('i',l)s:_('w',v)t:_('H',j)   u:_('a',a)v:_('o',a)w:_(')',k)   x:_('l',c)y:_('/t',g)z:___(0x0)}

hello4.c

  int n[]={0x48,  0x65,0x6C,0x6C,  0x6F,0x2C,0x20,  0x77,0x6F,0x72,  0x6C,0x64,0x21,  0x0A,0x00},*m=n;  main(n){putchar  (*m)!='/0'?main  (m++):exit(n++);}

hello5.c

  main(){int i,n[]={(((1<<1)<<(1<<1)<<(1<<  1)<<(1<<(1>>1)))+((1<<1)<<(1<<1))), (((1  <<1)<<(1<<1)<<(1<<1)<<(1<<1))-((1<<1)<<(  1<<1)<<(1<<1))+((1<<1)<<(1<<(1>>1)))+ (1  <<(1>>1))),(((1<<1)<<(1<<1)<<(1<<1)<< (1  <<1))-((1<<1)<<(1<<1)<<(1<<(1>>1)))- ((1  <<1)<<(1<<(1>>1)))),(((1<<1)<<(1<<1)<<(1  <<1)<<(1<<1))-((1<<1)<<(1<<1)<<(1<<(1>>1  )))-((1<<1)<<(1<<(1>>1)))),(((1<<1)<< (1  <<1)<<(1<<1)<<(1<<1))-((1<<1)<<(1<<1)<<(  1<<(1>>1)))-(1<<(1>>1))),(((1<<1)<<(1<<1  )<<(1<<1))+((1<<1)<<(1<<1)<<(1<<(1>>1)))  -((1<<1)<<(1<<(1>>1)))),((1<<1)<< (1<<1)  <<(1<<1)),(((1<<1)<<(1<<1)<<(1<<1)<<(1<<  1))-((1<<1)<<(1<<1))-(1<<(1>>1))),(((1<<  1)<<(1<<1)<<(1<<1)<<(1<<1))-((1<<1)<< (1  <<1)<<(1<<(1>>1)))-(1<<(1>>1))), (((1<<1  )<<(1<<1)<<(1<<1)<<(1<<1))- ((1<<1)<< (1  <<1)<<(1<<(1>>1)))+(1<<1)), (((1<<1)<< (  1<<1)<<(1<<1)<< (1<<1))-((1<<1)<< (1<<1)  <<(1<<(1>>1)))-((1<<1) <<(1<< (1>>1)))),  (((1<<1)<< (1<<1)<<(1<<1)<< (1<<1))- ((1  <<1)<<(1<<1)<<(1<<1))+((1<<1)<< (1<<(1>>  1)))), (((1<<1)<<(1<<1) <<(1<<1))+(1<<(1  >>1))),(((1<<1)<<(1<<1))+((1<<1)<< (1<<(  1>>1))) + (1<< (1>>1)))}; for(i=(1>>1);i  <(((1<<1) <<(1<<1))+((1 <<1)<< (1<<(1>>1  ))) + (1<<1)); i++) printf("%c",n[i]); }

hello6.cpp

下面的程序只能由C++的編譯器編譯（比如：g++）

  #include <stdio.h>  #define _(_) putchar(_);  int main(void){int i = 0;_(  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++i)_(++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++i)_(++++++++++++++  i)_(--++i)_(++++++i)_(------  ----------------------------  ----------------------------  ----------------------------  ----------------------------  ----------------i)_(--------  ----------------i)_(++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++++  ++++++++++++++++++++++++++i)  _(----------------i)_(++++++  i)_(------------i)_(--------  --------i)_(----------------  ----------------------------  ----------------------------  ----------------------------  ----------------------------  ------i)_(------------------  ----------------------------  i)return i;}
