基于Visual Stdio IDE，利用EasyX图形函数库工具搭建可视化图形操作界面。通过鼠标在图形界面上点击选子，实现了五子棋的双人对战小游戏。
本程序主体框架是从/ArchyLi/article/details/70446314学习来的，但其功能简单、界面简陋、程序功能还有漏洞，于是做出了一下修改。
添加功能：1.增加随时退出功能、2.增加重新开始功能、3.增加悔棋功能 4.增加总比分显示、5.增加落子提示
美化界面：从开始界面，游戏界面、到结束界面使用一些网上搜集来的图片作为背景，不再是黑白背景
修复漏洞及优化：1.修复了继续游戏时采用层层递归可能导致栈溢出的潜在问题、2.优化了判定胜利规则程序，不再是整个棋盘遍历。
2.效果展示
开始界面
正式游戏界面
结束界面
3.程序代码
采用的是C的面向过程的编程思想，以后会考虑改成C++面向对象的编程结构。关于字符集设置网上很多说设置成“多字节字符集”，但我的还是乱码。于是我将字符集设置成了“未设置”，字体就不乱码了。

4.问题与不足
待解决的问题：1.没有实现人机对战功能、2.不能两台电脑之间通信对战。
不足：1.程序比较冗余(需优化) 、2.变量管理复杂，经常遇到改一个变量要多处手动修改
5.附录图片
程序中用到的背景图图片直接跟源文件放到同一目录下即可
