六个最变态的C语言 Hello World

下面的六个程序片段主要完成这些事情：

1. 输出Hello, World
2. 混乱C语言的源代码

下面的所有程序都可以在GCC下编译通过，只有最后一个需要动用C++的编译器g++才能编程通过。

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++]-0x43;*(z++)=y[x]-0x21;

   }

hello3.c

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

   1)<<(1<<(1>>1)))+((1<<1)<<(1<<1))), (((1

hello6.cpp

下面的程序只能由C++的编译器编译（比如：g++）

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