之前写的俄罗斯方块在玩的过程中发现一个很不方便的地方是没有暂停的功能，于是准备加上。想实现的效果是按下空格键暂停，同时弹出一个对话框显示当前处于暂停状态，再按一下某个键便继续运行。
另外就是当游戏结束的时候，希望可以弹出一个对话框，提示“game over”，同时提示是要重新开始还是退出游戏，这个也是用带有按钮的对话框比较好。那么如何实现对话框并且判断被选择的是哪个按钮呢？在《NCURSES programing HOWTO》里有提到要实现对话框可以使用CDK。下载完CDK之后便是调用API绘制对话框了，感觉CDK的man手册还是很好的，很快就实现了，效果如下：
暂停提示：
game over提示：
要退出时提示：
虽然做出来的效果很简单，但是我个人还是挺喜欢在终端里这种简洁的感觉的。
照例贴出源代码，本人菜鸟一枚，非常希望有人可以对代码提出各种批评～
只对main.c文件做了修改。另外查了一下版本号的命令规则，UNIX的风格一般是从0.0.0或者0.1.0开始的，所以将版本号改为了V0.1.0
