相信不少人都听说过国际 C 语言混乱大赛吧？里面有不少看起来千奇百怪的代码，但却都是完整的 C 程序并且不少是非常有用并且高效的程序。今天我在这里又看到几个混乱过的 Hello World 程序，例如：

#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
_____

如果我不说，你能看出来它是一个打印 Hello World 的程序吗？还有这个（据说只能用 C++ 编译器编译）看起来是不是有点 Brainfuck 语言的味道？

#include 
#define _(_) putchar(_);
int main(void){int i = 0;_(

这个网站上还列举了不少这类似的程序，自己去看看吧！ :)
