linux下面的C编程，我还是新手，请大家别笑话。

/*
* Brick & Ball
* by Jerry Fleming <jerryfleming2006@gmail.com>
*
* This is a small game inspired from similar one in Motorola Mobile C289,
* and my first REAL program in C :) Please tell me if you have a better
* implementation or any suggestions.
*
* HISTORY:
* 2006-10-25: third (current) version with c language
* 2006-10-01: second version with tkinter
* 2006-04-19: first version with curses
*
* TODO:
* Nothing to do right now. :) If you have any ideas to improve or enhance it,
* please contact me.
