6个变态的C语言Hello World程序

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

01	#define _________ }

02	#define ________ putchar

03	#define _______ main

04	#define _(a) ________(a);

05	#define ______ _______(){

07	#define ___ _(0x6F)_(0x2C)_(0x20)_(0x77)_(0x6F)

08	#define ____ _(0x72)_(0x6C)_(0x64)_(0x21)

09	#define _____ __ ___ ____ _________
