这是一个用C语言编写的简单游戏，灵感来源于Motorola Mobile C289中的类似游戏。这是作者的第一个真正的C语言程序，游戏包括砖块、球和挡板等元素，玩家通过移动挡板反弹球来击打砖块得分。

2 * Brick & Ball
3 * by Jerry Fleming <jerryfleming2006@gmail.com>
4 *
5 * This is a small game inspired from similar one in Motorola Mobile C289,
6 * and my first REAL program in C :) Please tell me if you have a better
7 * implementation or any suggestions.
8 *
9 * HISTORY:
10 * 2006-10-25: third (current) version with c language
11 * 2006-10-01: second version with tkinter
12 * 2006-04-19: first version with curses
13 *
14 * TODO:
15 * Nothing to do right now. :) If you have any ideas to improve or enhance it,
16 * please contact me.
