扫雷小游戏的简单优化（1：困难模式 2：第一步走，不被炸死 3：无雷坐标可以展开）

初始化两个数组来储存数据，一个用来存放雷，一个显示

game.c

初始化，打印棋盘。

rang()%9 范围为0~8，rang()%9 + 1范围为1~9，方便玩家定位。

#include"game.h"
void InitBoard(char board[ROWS][COLS], int row, int col, char set)
{
	int i = 0;
	for (i = 0;i < ROWS;i++)
	{
		int j = 0;
		for (j = 0;j < COLS;j++)
		{
			board[i][j] = set;
		}
	}
}

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

void SetMine(char mine[ROWS][COLS], int row, int col,int count)
{
	int i = count;
	while (i)
	{
		int x = (rand() % 9) + 1;
		int y = (rand() % 9) + 1;
		if (mine[x][y] == '0')
		{
			mine[x][y] = '1';
			i--;
		}
	}
}

获取周边雷的个数

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

递归的形式坐标展开无雷坐标

int Expand(char mine[ROWS][COLS], char show[ROWS][COLS], int x ,int y,int win)
{
	if (x >= 1 && x <= ROW && y >= 1 && y <= COL)
	{
		
		if (GetMineCount(mine, x, y) == 0)
		{
			show[x][y] = ' ';
			if (show[x - 1][y - 1] == '*')
			{
				Expand(mine, show, x - 1, y - 1,win);
			}
			if (show[x - 1][y] == '*')
			{
				Expand(mine, show, x - 1, y,win);
			}
			if (show[x - 1][y + 1] == '*')
			{
				Expand(mine, show, x - 1, y + 1,win);
			}
			if (show[x][y + 1] == '*')
			{
				Expand(mine, show, x, y + 1,win);
			}
			if (show[x + 1][y + 1] == '*')
			{
				Expand(mine, show, x + 1, y + 1,win);
			}
			if (show[x + 1][y] == '*')
			{
				Expand(mine, show, x + 1, y,win);
			}
			if (show[x + 1][y - 1] == '*')
			{
				Expand(mine, show, x + 1, y - 1,win);
			}
			if (show[x][y - 1] == '*')
			{
				Expand(mine, show, x, y - 1,win);
			}
		}
	}
	return win;
}

移动雷，第一步不会结束

void RemoveMine(char mine[ROWS][COLS],int x,int y)
{
	if (mine[x][y] == '1')
	{
		mine[x][y] = '0';
		while (1) 
		{
			int x1 = rand() % (ROW)+1;
			int y1 = rand() % (COL)+1;
			if (mine[x1][y1] = '0')
			{
				mine[x1][y1] = '1';
				break;
			}
		}
	}
}

游戏循环

void FindMine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col,int count,int win)
{
	int x = 0;
	int y = 0;
	int i = 1;
	while (win < col*row - count)
	{
		printf("请输入坐标：");
		scanf("%d%d",&x,&y);
		while (i)
		{
			RemoveMine(mine, x, y);
			i--;
		}
		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			if (mine[x][y] == '1')
			{
				printf("炸弹爆炸，游戏结束\n");
				break;
			}
			else
			{
	
				if (GetMineCount(mine, x, y) == 0)
				{
					Expand(mine, show, x, y,win);
					Display(show, row, col);
				}
				else
				{
					win++;
					int c = GetMineCount(mine, x, y);
					show[x][y] = c + '0';
					Display(show,row,col);
				}
			
			}
		}
		else
		{
			printf("输入错误！\n");
		}
	}
	if (win == col * row - count)
	{
		printf("恭喜，排雷成功！\n");
	}
}

ASCLL表，字符‘1’对应49 ，‘0’对应48.

‘1’ - ‘0’ = 49 - 48 =1

所以字符型转换为整形减去48 或者减去‘0

整形转换为字符型加48 或加‘0’
