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

#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 

#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;

x=*(--z);while(y[x]!=NULL)putchar(y[x++]);

}

 

 

 

hello3.c

#include<stdio.h>

#define ___(a) putchar(a);

#define _(a,b) ___(a) __(b);

hello4.c

int n[]={0x48,

0x65,0x6C,0x6C,

0x6C,0x64,0x21,

0x0A,0x00},*m=n;

main(n){putchar

(*m)!='/0'?main

(m++):exit(n++);}

 

 

 

hello5.c

1)<<(1<<(1>>1)))+((1<<1)<<(1<<1))), (((1

hello6.cpp

下面的程序只能由C++的编译器编译（比如：g++）

#include <stdio.h>

#define _(_) putchar(_);

int main(void){int i = 0;_(
