6个变态的C语言Hello World程序

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

1 2 3 4 5 6 7 8 9 10 11

#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>     _____

hello2.c

1 2 3 4 5 6 7 8 9

#include<stdio.h>     main(){       int x=0,y[14],*z=&y;*(z++)=0x48;*(z++)=y[x++]+0x1D;       *(z++)=y[x++]+0x07;*(z++)=y[x++]+0x00;*(z++)=y[x++]+0x03;       *(z++)=y[x++]-0x43;*(z++)=y[x++]-0x0C;*(z++)=y[x++]+0x57;       *(z++)=y[x++]-0x08;*(z++)=y[x++]+0x03;*(z++)=y[x++]-0x06;       *(z++)=y[x++]-0x08;*(z++)=y[x++]-0x43;*(z++)=y[x]-0x21;       x=*(--z);while(y[x]!=NULL)putchar(y[x++]);     }

hello3.c

hello4.c

hello6.cpp

下面的程序只能由C++的编译器编译（比如：g++）

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34
