C language - minesweeping

Introduction to the game

Minesweeping is a popular game . The goal of the Chinese version of minesweeping is to find all non minesweeping grids in the shortest time according to the numbers that appear in the click grid , At the same time, avoid stepping on thunder .

Game design

Module processing ：

Initialize chessboard

void init_board(char arr[ROWS][COLS], int rows, int cols, char set)
{
    
	int i = 0;
	int j = 0;
	for (i = 0; i < rows; i++)
	{
    
		for (j = 0; j < cols; j++)
		{
    
			arr[i][j] = set;
		}
	}
}

Print chessboard

void show_board(char arr[ROWS][COLS], int row, int col)
{
    
	int i = 0;
	int j = 0;
	printf("---------- Mine clearance -----------\n");
	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 ", arr[i][j]);
		}
		printf("\n");
	}
	printf("---------- Mine clearance ------------\n");
}

Arrange thunder

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

Check the thunder

void find_mine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col)
{
    
	int x = 0;
	int y = 0;
	int win = 0;
	while (win < row * col - EASY_COUNT)
	{
    
		printf(" Please enter the coordinates to be checked ：>");
		scanf("%d %d", &x, &y);
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
    
			if (mine[x][y] == '1')
			{
    
				printf(" unfortunately , You were blown up \n");
				show_board(mine, ROW, COL);
				break;
			}
			else
			{
    
				int count = get_mine(mine, x, y);
				show[x][y] = count + '0';
				show_board(show, ROW, COL);
				win++;
			}

		}
		else
		{
    
			printf(" illegal input , Re input \n");

		}
		if (win == row * col - EASY_COUNT)
		{
    
			printf(" congratulations , Mine clearance is successful \n");
			show_board(mine, ROW, COL);
		}
	}
}

Determine the number of surrounding mines during demining

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