1.打印菜单

1、菜单页面,实现三子棋我们得先制作一个菜单界面，

输入1则进入游戏，2则退出游戏

 

void meat()//打印菜单
{
	printf("---------------------n");
	printf("-----1.开始游戏------n");
	printf("-----2.退出游戏------n");
	printf("---------------------n");
	printf("---------------------n");
 }

2.棋盘初始化

2.用一个三行三列的二维数组 char类型，进行初始化。

InitBoard(char board[ROW][COL], int row, int col)//初始化棋盘
{
	int i = 0;
	int j = 0;
	for (i = 0; i <= row; i++)
	{
		for (j = 0; j <= col; j++)
		{
			board[i][j] = ' ';
		}
	}
}

3.打印棋盘

dispalyBoard(char board[ROW][COL], int row, int col)//打印棋盘
{
	printf("+---+---+---+n");
	int i = 0;
	for (i = 0; i < row; i++)
	{
		printf("| %c | %c | %c |n", board[i][0], board[i][1], board[i][2]);
		printf("+---+---+---+n");
	}
	printf("n");
}

     打印效果

 写到这里就可以开始下棋了。

4.玩家落子

void playerMove(char board[ROW][COL], int row, int col)//玩家下棋
{
	int x = 0;
	int y = 0;
	printf("玩家下棋>:n");
	while (1)
	{
		printf("请输入坐标>:");
		scanf("%d %d", &x, &y);
		//坐标是否合法;
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (board[x - 1][y - 1] == ' ')//判断是否有落子
			{
				board[x - 1][y -1] = 'x';
					break;
			}
		}
		else
		{
			printf("坐标被占用，请换位n");
		}
	}
 }

  玩家输入行列坐标落子。

玩家要下在棋盘范围内或是空位，如果不符合要求会要求玩家重新输入！！

4.电脑下棋

 srand((unsigned int)time(NULL));
void ComputerMoce(char board[ROW][COL], int row, int col)//电脑下棋
{
	printf("电脑下棋:>n");
	int x = 0;
	int y = 0;
	
		
		while (1)
		{
			x = rand() % row;
			y = rand() % col;
			if (board[x][y] == ' ')
			{
				board[x][y] = 'o';
				break;
			}
		}
}

电脑下棋利用srand((unsigned int)time(NULL));生成一个随机数(记得引用头文件)，再用随机数%上3得到一个0~2的随机数，用这种方式就不用判断是否合法，只需要判断是否落子,这是最最最简易的方法，但是人机的下法非常随机非常好赢，这时候就可以给人机加入一些算法来提高人机的胜率。

 5.判断输赢

char Iswin(char board[ROW][COL], int row, int col)
{
	//判断行
	int i = 0;
	for (i = 0; i < row; i++)
	{
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2]&& board[i][1] != ' ')
		{
			return board[i][1];
		}
	}
	//判断列
	int j = 0;
	for (j = 0; j < col; j++)
	{
		if (board[0][j] == board[1][j] && board[1][j] == board[2][j] && board[1][j] != ' ')
		{
			return board[1][j];
		}
	}
	//判断对角线
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}

    if (ret == 'x')
	{
		printf("玩家赢了！n");
	}
	else if (ret == 'o')
	{
		printf("电脑赢了！n");
	}
	else 
	{
		printf("平局n");
	}

返回x则玩家赢返回o则电脑赢。

6.判断是否平局

int IsFull(char board[ROW][COL], int row, int col)
{
	int i = 0;
	int j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			if (board[i][j] == ' ')
			{
				return 0;//判断还有空格继续游戏。
			}
		}
	}
	return 1;
}
