C语言实现三子棋（不是人工智障哈哈哈）

下面就是这段代码所对应的棋盘啦

(4)、玩家下棋

棋盘打印好之后相当于准备工作就做好了，接下来就是玩家与电脑的博弈啦。

首先是玩家下棋，“*”代表玩家，先由玩家输入第几行第几列，落子之前，系统要先判断该位置是否不被占用，输入是否合法，只有都满足才能落子，否则就要重新输入，下面是代码实现：

void player_move(char board[ROW][COL]){	int i = 0;	int j = 0;		while (1)	{		scanf("%d %d", &i, &j);		if (i >= 0 && i < ROW && j >= 0 && j < COL)		{			if (board[i][j] == " ")			{				board[i][j] = "*";				DisplayBoard(board);				return;			}			else				printf("该位置已被占用，请重新输入！  ");		}		else			printf("输入不合法，请重新输入!");	}}

(5)、电脑下棋

这里就不得不说一下实现人工智能是真的有点难度，我最开始写电脑落子的时候是直接利用srand（）和rand（）函数来随机生成两个数作为落子的坐标的，后来发现写出来的游戏整个就一人工智障，然后稍稍改变了电脑下棋这一部分函数，才让电脑学会堵玩家的棋子，而不是只是单单随便下了。电脑落子前我是先让它判断是否有某一行或某一列或对角线上已经有2个玩家落的棋子了，如果有，则直接将电脑的棋子落在相应的位置上去堵玩家，如果没有在去随机生成2个数去确定自己的位置（我还没有实现怎么让电脑除了堵别人还有自己的走法），要不怎么说人工智能难呢，我们还是来看看这部分是怎么实现的吧

void computer_move(char board[ROW][COL]){	while (1)	{		int i = 0;		int j = 0;		for (i = 0; i < ROW; i++)//判断一行中是否有两个相同的		{			if (board[i][0] == " "&&board[i][1] == board[i][2] && board[i][1] !=" " || board[i][1] == " " && board[i][0] == board[i][2] && board[i][0] != " " || board[i][2] == " " && board[i][1] == board[i][0] && board[i][1] != " ")			{				for (j = 0; j < COL; j++)				{					if (board[i][j] == " ")					{						board[i][j] = "#";						DisplayBoard(board);						return;					}				}			}					}				for (i = 0; i < ROW; i++)//判断一列中是否有两个相同的		{			if (board[0][i] == " "&&board[1][i] == board[2][i] && board[1][i]!=" " || board[1][i] == " " && board[0][i] == board[2][i] && board[0][i] != " " || board[2][i] == " " && board[0][i] == board[1][i] && board[0][i] != " ")//判断列			{				for (j = 0; j < COL; j++)				{					if (board[j][i] == " ")					{						board[j][i] = "#";						DisplayBoard(board);						return;					}				}			}					}						//判断主对角线中是否有两个相同的		if (board[1][1] != " " && board[2][2] == board[1][1] || board[0][0] != " " && board[0][0] == board[1][1] || board[2][2] != " " && board[0][0] == board[2][2])		{			for (j= 0; j < ROW; j++)			{				if (board[j][j] == " ")				{					board[j][j] = "#";					DisplayBoard(board);					return;				}			}		}					//判断副对角线是否有两个相同的		if (board[2][0] != " " && board[2][0] == board[0][2] || board[1][1] !=" " && board[1][1] == board[2][0] || board[1][1] !=" " && board[1][1] == board[0][2])		{			for (j = 0; j < ROW; j++)			{				if (board[2 - j][j] == " ")				{					board[2 - j][j] = "#";					DisplayBoard(board);					return;				}			}		}			//随机下棋		int a = rand() % ROW;		int b = rand() % COL;		if (board[a][b] == " ")		{			board[a][b] = "#";			DisplayBoard(board);			break;		}	}}

玩家下棋和电脑下棋是放在一个循环里面的，直到三子连线或棋盘被下满嘛，接下来的一步就是判断输赢啦

 (6)、判断输赢

这个主要就是用循环来写，判断一行或一列或对角线上的字符都是同一个且不是空格就可以决出胜负啦，然后返回对应的字符稍加判断就可以知道谁是赢家啦。当然，如果棋盘满了也就是没有二位数组中空格且没有三子连线就可以判为平局。看代码：

int ful_board(char board[ROW][COL])//判断棋盘是否满{	int i = 0;	int j = 0;	for (i = 0; i < ROW; i++)	{		for (j = 0; j < COL; j++)		{			if (board[i][j] == " ")				return 0;		}	}	return 1;}char win(char board[ROW][COL])//判断输赢{	int i = 0;	int j = 0;	for (j = 0; j < COL; j++)	{		if (board[0][j] == board[1][j] && board[0][j] == board[2][j]&& board[0][j] != " ")//判断列			return board[0][j];			}	for (j = 0; j < COL; j++)	{		if (board[j][0] == board[j][1] && board[j][0] == board[j][2]&& board[j][0] != " ")//判断行			return board[j][0];	}	if (board[0][0] == board[1][1] && board[0][0]==board[2][2] && board[0][0] != " ")	{		return board[1][1];	}	if (board[0][2] == board[1][1] && board[1][1] == board[2][0]&& board[0][2] != " ")	{		return board[1][1];	}	if (1 == ful_board(board))		return "P";	return 0;}

以上就是各个函数的具体实现了，我是把这些函数大都放在game.c中，然后在game.c中声明它们，最后在test.c中测试时就可以直接引用头文件game.c啦，接下来就让我们来看看整个完整的代码~~

到这里就结束啦，接下来我还会写一个扫雷的小游戏的哈哈哈，最后看完的小伙伴给个赞吧
