6个变态的C语言Hello World程序_C 语言

下面的六个程序片段主要完成这些事情：

输出Hello, World
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>
