2、目计算机网络课程设计局域网五子棋的实现二、设计的任务、目的和作用计算机网络课程设计是计算机网络原理课程之后的时间加强环节，通过本设计的训练使学生加深对网络协议的理解，并实现制定通信规则，同时通过实践，进一步掌握套接字编程方法，为大型网络编程打下坚实基础。三、课程设计的内容五子棋的局域网对战四、开发环境及实现所用语言开发环境：Microsoft Visual C+ 6.0语言： C+ 五、实现要点A、数据通信指令（协议）及各指令的处理内容客户与服务器采用 TCP 连接指令及处理：#define LOGINSERVER login /连接服务器#define LEAVESERVER leave /
