Description: 我编写了一个“天文数字计算”程序突破了这一限制，可以把数字的长度扩充到无穷多位。除了能做加、减、乘、除、求模等基本运算外还可以做阶乘、乘方、开平方等运算。
例如：10000! = ?、(2002^2000)%9999 = 9394、2002的平方根的小数点后第10000位是4。
下面这个程序只是我用编写的“天文数字计算”里的一个计算。
因为在程序代码中使用了中文，所以这个程序如果不在中文DOS下运行，可能会出现乱码，但不影响程序的计算结果。
注：因为DOS能访问的内存有限，所以在DOS下可把计算结果扩充到30000多位。但如果用VC把它编绎成Windows程序，则可以计算到“真正的无穷多位”（与机子配置有关），一般计算到几十万位是没有问题的。

Description: 本次project实现如下功能：
写了一个本地的多线程游戏服务器ThreadeEchoServer，地址和端口为：127.0.0.1：9999
写了一个本地的多线程游戏客户端client，用来连接服务器，并进行通信．
在客户端下可以启动两个小游戏：连连看和俄罗斯方块．都需要网络服务器做出响应才能启动，可以建立客户的多线程，也就是多个客户连服务器．同时可以在一个客户实现同时玩两个游戏．
两个游戏的代码改编于网络公布的源代码，原来的源代码有很多错误和不足，给出了合适我们的修正．
运行方式：先编译生成所有的class文件，本地启动服务器，再启动客户端，在客户端进行选择操作，来启动游戏，按面板提示进行游戏，最后退出客户端即可．
开发工具：jCreat
开发人员：曾捷 -this project to achieve the following functions : writing a multithreaded local game servers ThreadeEchoServer, addresses and ports : 127.0.0.1:9999 was a local multithreaded game client client, used to connect to servers, and communications. The client can be activated under two small games : 1000 block of Terry Avenue and Tetris. Need to respond to network servers can be initiated, can build customer multithreading, which is even more customers servers. At the same time, a customer can simultaneously play two games. Two games based on code released by the network source code, the original source code with a lot of mistakes and shortcomings, and we have given appropriate amendments. Operation : compiler generates all the first class of documents, local boot server, Restart client, the cli
