三子棋功能实现

下棋流程

打印棋盘

初始化棋盘函数

初始化的必要性说明 如果不将棋盘初始化 下棋的时候就会出现 判断的bug

void lnitboard(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++)
		{
			board[i][j] = ' ';
		}
	}
}

打印棋盘

代码分析
通过列数控制最小单元打印次数
通过行数控制需要打印多少

void displayboard(char board[ROW][COL], int row, int col)
{
	int i = 0;
	for (i = 0; i < row; i++)
	{
		int j = 0;
		for (j = 0; j < COL; j++)
		{
			printf(" %c |", board[i][j]);

		}
		printf("\n");

		for (j = 0; j < COL; j++)
		{
			printf("---|");
		}
		printf("\n");
	}


}

玩家下棋

玩家下棋需求
1 不能超出棋盘范围
2 已经下了不能在下
3 一次只能走一步
4 玩家二和玩家一下棋方法为一致的
1和2 我们通过if条件语句 不满足则 不能下 继续循环 满足则跳出循环

void playermove(char board[ROW][COL], int row, int col)
{
	int x = 0;
	int y = 0;
	while (1)
	{
		printf("玩家走→");
		printf("请输入坐标");
		scanf("%d%d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col) //满足1 2条件可跳出循环
		{
			if (board[x - 1][y - 1] == ' ')
			{
				board[x - 1][y - 1] = '*';
				break;
			}
			else
			{
				printf("该坐标已经被占用");
			}

		}
		else {
			printf("坐标不合法");
		}
	}
}

电脑下棋

电脑下棋为产生随机数
想进一步了解随机数产生机制 戳这里 随机数产生

void cpmove(char board[ROW][COL], int row, int col)
{
	printf("电脑走\n");
	while (1)
	{
		
		int x = rand() % row;
		int y = rand() % col;
		
		
			if (board[x ][y ] == ' ')
			{
				board[x ][y] = '#';
				break;
			}
		

		
		
	}
}

胜负判定

三子棋赢的方式有三种 一行 一列 一条对角线 三字相同即可
也要注意平局和棋盘下满了

char iswin(char board[ROW][COL], int row, int col)
{

	int i = 0;
	for (i = 0; i < row; i++)
	{
		//printf("%c%c%c", board[i][0], board[i][1], board[i][2]);
		if (board[i][0] == board[i][1] && board[i][1] == board[i][2] && board[i][1] != ' ')
		{

			return board[i][1];
			break;
		}
	}
	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];
			break;
		}
	}
	if (board[0][0] == board[1][1] && board[1][1] == board[2][2] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	else if (board[0][2] == board[1][1] && board[1][1] == board[2][0] && board[1][1] != ' ')
	{
		return board[1][1];
	}
	else if (full(board, ROW, COL) == 0)
	{

		return 'a';
	}
	else
		return 'c';
}

如果棋盘满了就将数据导入full(棋盘满了返回0)提示平局
