用ncurses.h写的一个俄罗斯方块游戏，不过只是代码加makefile 在命令行里面可以先简单试一下，主要是让人们能看懂俄罗斯方块游戏设计的原理。这个本来是我们上C++课老师留的作业，刚开始我也是没有任何思路，后来找了很多俄罗斯方块源代码也没有用ncurses.h来写的，所以我觉得发一个，虽然很简单，但难免以后也会有人需要

重点讲解正则表达式的用法，用以实现全文搜说的表达式定义。-The usage of the regular expression is discussed in detail in order to offer appropriate reference to the search engine development.

80C51的串行通信口是一个功能强大的通信口，而且是相当好用的通信口，用于显示驱动电路再合适不过了，下面我们就根据这种需要设计一个用两个串行通信口线加上两根普通I/O口，设计一个4位LED显示电路。当然只要再加上两根I/O口线即可轻易实现8位LED的显示电路。 -80C51 Serial Communications mouth is a powerful communications mouth, but is very handy communications mouth, for the display driver circuit could not have been more appropriate, Now we need to design the basis of this one with two serial communication lines with two general I/O Hau, Design of a four LED display circuit. Of course if coupled with two I/O lines I could easily achieved eight LED display circuit.

This game is a demonstration of pulling cards from the cards.dll File. I m not sure who the author of the cards.bas module is but it is off the hook. Kudos to whoever wrote that.
