C/S 类型网络编程练习 猜数游戏

题目三：猜数游戏软件名：猜数游戏（分服务器端和客户端两部分）功能：游戏后台运行一个服务器软件，游戏者通过客户端程序登陆后，服务器随机产生一个1—100之间的随机数供游戏者猜，游戏者从客户端输入一个数值，如果该数比设定的数大，软件提示：“大了”，如果小，软件提示“小了”，若相等返回“猜对了，你共猜了*次”。服务器同时记录并维护一个游戏玩家的TOP10排行榜，供玩家查询。编程语言及工具：自选（如VB、JAVA、C#、Delphi、VC）描述：服务器端：接收客户端的命令请求并提供相应的服务。客户端：完成游戏人机界界面的设计，以命令的方式向服务器请求服务，并显示相应的提示。主要的命令有：1．CONNECT IP地址 端口号指定游戏服务器的IP地址和端口号，连接到服务器。响应：连接成功/失败。2．LOGIN 用户名用户登录，报告服务器玩家的名字。响应：成功/失败。3．GUESS 数字猜数。响应：大了/小了/对了。4．LISTTOP10请求显示TOP10排行榜。响应：显示TOP10排行榜。5．EXIT退出游戏。Client:
