6个变态的C语言写的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

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;_(
