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。

  #include <stdio.h>    #define _(_) putchar(_);    int main(void){int i = 0;_(    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++i)_(++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++i)_(++++++++++++++    i)_(--++i)_(++++++i)_(------    ----------------------------    ----------------------------    ----------------------------    ----------------------------    ----------------i)_(--------    ----------------i)_(++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++++    ++++++++++++++++++++++++++i)    _(----------------i)_(++++++    i)_(------------i)_(--------    --------i)_(----------------    ----------------------------    ----------------------------    ----------------------------    ----------------------------    ------i)_(------------------    ----------------------------    i)return i;}
