本系统是基于Asp.Net框架，利用C#编程语言开发的餐饮管理系统，实现了顾客点餐，统计支付，并有点外卖功能，管理员可以管理菜品（比如上传图片），人事调动（增删改查信息），并配有开发报告。

最近项目用到播放RTSP视频流,研究了一阵子,初步写了个demo,放出源码,QT实现RTSP视频流播放这块例子比较少,而且大部分不可用,不是缺lib库就是缺运行库等,就算几个可用的VLC,QTAV,播放视频的速度及画面呈现质量实在不敢恭维,特意编写了此DEMO,全部放出代码以供学习

本程序的目的数据结构是一个储存所有子集集合的一个结构体，包含子集中所有的状态，利用邻接表实现。
算法正如书上所说，子集构造算法如下：
假定所构造的子集族为C，即C= (T1, T2,,... TI),其中T1, T2,,... TI为状态K的子集。
（1）开始，令-closure(K0)为C中唯一成员，并且它是未被标记的。
（2）while （C中存在尚未被标记的子集T）do
{
标记T；
for 每个输入字母a do
{
U:= -closure(move(T,a));
if U不在C中 then
将U作为未标记的子集加在C中
}
}
输入文本格式样例：
A B C D E F G H I J K L M N O P Q R S T #
A a B
C * D
E a F
G d H
M a N
O d P
Q * M
