? ? ? ?三子棋 ，也叫井字棋，是一款大家都玩过的经典小游戏，也是一个适合初学c语言的小伙伴练练手的小项目。
? ? ? ? 1.整个棋盘采用二维数组存储，下棋时只要获取到x,y两个方向的坐标访问二维数组中的元素改变存储的字符串样式。
? ? ? ? 2.判断输赢或平局，直接穷举就行了，判断每行、每列、和对角线是否有三个棋子相连。可设置一个带返回值的检查函数，根据不一样的返回值进行不同操作。
? ? ? ? 3.其余的页面菜单，和棋盘打印。只需要合理利用循环和判断来打印相关内容，很容易就能实现了。
????????效果展示

? ? ? ? ?附上全部源码，大家可以在自己的编译器上跑一下试一试。?
