联机五子棋小程序：C++ MFC创建游戏界面

利用C++，通过MFC搭建游戏界面，制作了一个可以在局域网内联机对战的五子棋小程序，在小程序中添加了电脑玩家角色，用以辅助对战（也可以将电脑玩家角色独立出来做成单机版）

下面对程序作简要说明

（1）由于是联机游戏，双人对战，所以网络部分采用了客户端/服务器的模式。采用的Socket基类为MFC中封装的 CAsyncSocket。

（2）程序分为客户端和服务器。其中客户端部分包含三个部分：

a)chess MFC界面和游戏响应部分

b)nettask 网络交互部分

c)AIStratege 电脑玩家算法部分

其中服务器部分仅包含界面和网络交互部分

（3）MVS2017作为编译器

先给出最终的效果：

下面为完整的详细源码：
