C语言扫雷

头发没有代码多 人气:0

用户选择菜单

void menu()
{
	printf("****************************\n");
	printf("********  1.play  **********\n");
	printf("********  0.exit  **********\n");
	printf("****************************\n");
}

棋盘初始化

void Itnboard(char board[ROWS][COLS], int rows, int cols,char c)
{
	int i, j;
	for (i = 0; i < rows; i++)
	{
		for (j = 0; j <cols; j++)
		{
			board[i][j] = c;
		}
	}
}

创建数组,并对其进行初始化

布置雷(随机布置)

void Setboard(char board[ROWS][COLS], int row, int col)
{
	int count = Easy_count;
	while (count)
	{
		int x = rand() % row+1;
		int y = rand() % col+1;
		if (board[x][y] == '0')
		{
			board[x][y] = '1';
			count--;
		}
	}
}

用time函数产生随机值

打印棋盘

void Displayboard(char board[ROWS][COLS], int row, int col)
{
	int i, j;
	for (i = 0; i <= col; i++)
	{
		printf("%d ", i);
	}
	printf("\n");
	for (i = 1; i <= row; i++)
	{
		printf("%d ", i);
		for (j = 1; j <= col; j++)
		{
			printf("%c ", board[i][j]);
		}
		printf("\n");
	}
}

打印棋盘

玩家下棋

void Player(char board[ROWS][COLS], char show[ROWS][COLS], int row, int col)
{
	int x, y;
	int count = 0;
	while (1)
	{
		printf("请排雷:\n");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= 9 && y >= 1 && y <= 9)
		{
			if (board[x][y] == '0')
			{
				Openboard(show, board, x, y);
				Displayboard(show, ROW, COL);
			}
			else if (board[x][y] == '1')
			{
				printf("你死了\n");
				break;
			}
		}
		else
		{
			printf("请重新输入");
		}
		int i, j;
		for (i = 1; i <= row; i++)
		{
			for (j = 1; j <= col; j++)
			{
				if (show[i][j] == '*')
				{
					count++;
				}
			}
		}
		if (count == Easy_count)
		{
			printf("成功\n");   //这里的判断条件是遍历整个数组,统计雷的个数,如果雷的个数等于所剩余未排的*,说明排雷成功
			break;
		}
	}
}

用户输入值,并进行判断,如果该位置没有雷,我们进入展开函数

棋盘展开

void Openboard(char show[ROWS][COLS], char board[ROWS][COLS], int row, int col)
{
	if (row >= 1 && row <= ROW && col >= 1 && col <= COL)
	{
		int count=sum(board, row, col);
		if (count != 0)
		{
			show[row][col] = count + '0';
		}
		else if (show[row][col] != '_')
		{
			show[row][col] = '_';
			int i = 0, j = 0;
			for (i = row - 1; i <= row + 1; i++)
			{
				for (j = col - 1; j <= col + 1; j++)
				{
					Openboard(show, board, i,j);
				}
			}
		}
		else
		{
			return;
		}
	}
}

如果用户输入的这个位置没有雷,我们对其周围8个位置进行判断是否有雷,若有雷,我们把雷的个数显示在该位置上,若其周围8个位置没有雷并且不是下划线,我们把这个位置赋值为下划线,然后并对其8个位置进行同样的判断,如果周围没雷,而且周围的棋子也不是下划线,我们对其进行返回。

展开部分思维导图

展开函数最后一个else return 作用

这里我们show棋盘有三种情况,

1.该位置是*

2.该位置是下划线

3.该位置是雷的个数

else

return;

这里是作用:如果是下划线,我们就返回上一层函数。因为如果这里不是下划线,我们会在else return 之前的语句中进行判断,并对其周围8个位置进行操作,然后再对这8个棋子各个周围8个位置进行判断并操作,如果这里是下划线,就说明由这个位置为中心的周围8个棋子已经判断过了,并且以这8个位置为中心,已经递归过了,我们不需要再进行判断,所以直接返回就行

周围雷个数判断

int sum(char board[ROWS][COLS], int x, int y)
{
	return (board[x - 1][y - 1] +
		board[x - 1][y] +
		board[x - 1][y + 1] +
		board[x][y - 1] +
		board[x][y + 1] +
		board[x + 1][y - 1] +
		board[x + 1][y] +
		board[x + 1][y + 1] - 8 * '0');
}
