6个变态的C语言Hello World程序

估计每个学习编程的小毛头们,都是从hello world这个程序开始的吧,也估计大家闭着眼睛也能写代码来,但是

事实上,有些东西往往会很有趣,看下面,呵呵

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 ______ _______(){
06     #define __ ______ _(0x48)_(0x65)_(0x6C)_(0x6C)
07     #define ___ _(0x6F)_(0x2C)_(0x20)_(0x77)_(0x6F)
08     #define ____ _(0x72)_(0x6C)_(0x64)_(0x21)
09     #define _____ __ ___ ____ _________
10     #include
11     _____

 

hello2.c 

1     #include

hello6.cpp

下面的程序只能由C++的编译器编译(比如:g++)

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