扫雷（展开）（C语言）

 扫雷游戏介绍：输入判断的非雷坐标，判断错误则游戏失败，显示棋盘中雷布局情况，退出游戏，选择退出或重新开始。判断成功，若相邻坐标内有雷则记录相邻雷的个数，无雷则递归展开周围坐标。继续输入判断的非雷坐标，直至剩余未判断坐标总数与设置雷数相等则游戏胜利，选择退出或重新开始。

1.对应的头文件以及函数声明

#define _CRT_SECURE_NO_WARNINGS
#include
#include
#include
#include

#define ROW 9    //棋盘行数
#define COL 9    //棋盘列数

#define ROWS ROW+2  //防止访问越界
#define COLS COL+2  //防止访问越界

#define MineCounts 10   //设置雷的数量

//初始化棋盘
void InitBoard(char board[ROWS][COLS], char set);

//打印棋盘
void DisplayBoard(char board[ROWS][COLS]);

//布置雷
void SetMine(char board[ROWS][COLS]);

//排雷
void SerachMine(char mine[ROWS][COLS], char show[ROWS][COLS]);

2.对应函数功能的实现

//初始化棋盘
void InitBoard(char board[ROWS][COLS], char set)
{
	for (int i = 0; i < ROWS; i++)
	{
		for (int j = 0; j < COLS; j++)
		{
			board[i][j] = set;
		}
	}
}

//打印棋盘
void DisplayBoard(char board[ROWS][COLS])
{
	printf("-------- 扫雷 -------n");
	for (int i = 0; i <= COL; i++)
	{
		printf("%d ", i);
	}
	printf("n");
	for (int i = 1; i <= ROW; i++)
	{
		printf("%d ", i);
		for (int j = 1; j <= COL; j++)
		{
			printf("%c ", board[i][j]);
		}
		printf("n");
	}
	printf("-------- 扫雷 -------n");
}

//设置雷
void SetMine(char board[ROWS][COLS])
{
	int nums = MineCounts;
	while (nums)
	{
		int x = rand() % ROW + 1;
		int y = rand() % COL + 1;
		if (board[x][y] == '0')
		{
			board[x][y] = '1';
			nums--;
		}
	}
}

//统计不是雷的周围有几个雷
int RoundMineCount(char board[ROWS][COLS], int x, int y)
{
	return (board[x - 1][y] +
		board[x - 1][y - 1] +
		board[x][y - 1] +
		board[x + 1][y - 1] +
		board[x + 1][y] +
		board[x + 1][y + 1] +
		board[x][y + 1] +
		board[x - 1][y + 1] - 8 * '0');
}

//展开
void open(char mine[ROWS][COLS], char show[ROWS][COLS], int x, int y)
{
	if (x > 0 && x <= ROW && y > 0 && y <= COL)
	{
		int count = RoundMineCount(mine, x, y);
		if (count != 0)
		{
			show[x][y] = count + '0';
		}
		else if (show[x][y] == '*')
		{
			show[x][y] = ' ';
			int i = 0;
			int j = 0;
			for (i = x - 1; i <= x + 1; i++)
			{
				for (j = y - 1; j <= y + 1; j++)
				{
					open(mine, show, i, j);
				}
			}
		}
		else
		{
			return;
		}
	}
}

//排雷
void SerachMine(char mine[ROWS][COLS], char show[ROWS][COLS])
{
	int x = 0;
	int y = 0;
	int num = 0;
	while (1)
	{
		printf("请输入坐标>");
		scanf("%d %d", &x, &y);
		if (x > 0 && x <= ROW && y > 0 && y <= COL)
		{
			if (mine[x][y] == '1')
			{
				printf("你被炸死了！n");
				break;
			}
			else
			{
				if (show[x][y] != '*')
				{
					printf("坐标已被扫过！n");
				}
				else
				{
					system("cls");
					//show[x][y] = RoundMineCount(mine, x, y) + '0';
					open(mine, show, x, y);
					DisplayBoard(show);
				}
			}
		}
		else
		{
			printf("坐标非法！n");
		}
		for (int i = 1; i <= ROW; i++)
		{
			for (int j = 1; j <= COL; j++)
			{
				if (show[i][j] == '*')
				{
					num++;
				}
			}
		}
		if (num == MineCounts)
		{
			printf("恭喜你，胜利了!n");
			DisplayBoard(mine);
			break;
		}
		num = 0;
	}
}

3.测试

#include"game.h"

void game()
{
	char mineboard[ROWS][COLS] = { 0 };
	char showboard[ROWS][COLS] = { 0 };

	InitBoard(mineboard, '0');
	InitBoard(showboard,'*');
	SetMine(mineboard);

	DisplayBoard(showboard);
	SerachMine(mineboard, showboard);
	DisplayBoard(mineboard);
}

int main()
{
	srand((unsigned int)time(NULL));
	int input = 0;
    printf("请选择>n");
	do
	{
		printf("1.playn");
		printf("0.exitn");
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			break;
		default:
            printf("选择错误，请重新选择！n");
			break;
		}
	} while (input);
	return 0;
}
