首先做出初始界面,让玩家选择游戏或退出,选择游戏则进入游戏函数,用二维数组做出棋盘,初始化并打印,初始化是将棋盘中的落子处全部变为空格,如果不初始化填充的是0,接着是玩家落子,电脑落子,每次落子只允许落在空格处,每一次落子后都要判断游戏状态,一共4种状态,“玩家赢”、“电脑赢”、“继续”、“平局”。从而需要一个判断函数,将赢的情况都列出(横三行、竖三列、对角线),返回落子符号,没人赢即继续,平局即棋盘已满,除继续外三种情况直接结束游戏。电脑落子使用的是随机落子在空格处的方法。
void menu()

具体函数的实现如下

{
printf(" %c ",board[i][j]);
if (j < col - 1)
printf("|");
}
printf("\n");
if (i < row - 1)
{
for (j = 0; j < col; j++)
{
printf("---");
if (j < col - 1)
printf("|");
}
printf("\n");
}
}
}
void PlayerMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;
printf("玩家走:>\n");
while(1)
{
printf("请输入坐标:>");

{

{
board[x - 1][y - 1] = '*';
break;
}
else printf("该坐标被占用");
}
else printf("该坐标不合法,请重新输入\n");
}
}
void CompMove(char board[ROW][COL], int row, int col)
{
int x = 0;
int y = 0;

while (1)

}
}
}

{
int j = 0;

{

return 0;
}
}
return 1;
}

}

}
//对角线

//平局
