利用C语言实现人机三子棋游戏

利用C语言实现人机三子棋游戏

三子棋实现效果

1.首先游戏界面是一个选择进入游戏或者退出游戏的简单界面。
2.进入游戏之后出现的是一个3*3的一个棋盘。
3.玩家通过输入棋盘坐标下棋，机器随机落子。
4.游戏结束后可以选择继续游戏或者退出游戏。

实现代码

先上代码。

void InitBoard(char board[Row][Col], int row, int col);

//电脑下棋
void ComputerMove(char board[Row][Col],int row,int col);
//判断谁赢
char CheckWin(char board[Row][Col], int row, int col);
