【杂谈】如何高逼格的编写C语言Hello World程序

true

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

1. #define _________ }
   
2.     #define ________ putchar
   
3.     #define _______ main
   
4.     #define _(a) ________(a);
   
5.     #define ______ _______(){
   
6.     #define __ ______ _(0x48)_(0x65)_(0x6C)_(0x6C)
   
7.     #define ___ _(0x6F)_(0x2C)_(0x20)_(0x77)_(0x6F)
   
8.     #define ____ _(0x72)_(0x6C)_(0x64)_(0x21)
   
9.     #define _____ __ ___ ____ _________
   
10.     #include<stdio.h>

9.     }
