完成一个三子棋游戏的实现包括三部分

test.c 测试游戏

game.c 实现游戏

game.h 声明游戏

菜单

首先我们完成游戏的菜单部分

游戏部分

完成三子棋我们需要完成棋盘的创建，玩家下棋，电脑下棋，判断胜负，以及将棋盘展现给玩家，

这里我们用函数实现分为多个函数，在game.h中声明函数，在game.c中实现函数

 这里定义完行列，便于以后修改为多子棋

创建初始化棋盘

我们创建一个二维数组来存储3x3的棋盘

 打印棋盘

玩家下棋

 电脑下棋

rand函数来取随机数

需要添加srand函数，srand（(unsigned int)time(NULL))

 判断胜负

玩家赢返回 *

电脑赢返回 #

平局返回 q

游戏没结束返回 C

这里用isfull函数来判断棋盘有没有满，如果满了且玩家和电脑都没有赢的话则是平局，如果没满，且玩家和电脑都没有赢则继续游戏
