10. 扫雷游戏

和三子棋思路类似,先把整个游戏的大体结构实现出来:

代码语言:javascript复制
//game.h

#include <stdio.h>
代码语言:javascript复制
//test.c

#include "game.h"

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

int main()
{
	int input = 0;

	do
	{
		menu();
		printf("请选择:>");
		scanf("%d", &input);

		switch (input)
		{
		case 1:
			game();
			break;
		case 0:
			printf("退出游戏n");
			break;
		default:
			printf("选择错误,重新选择n");
			break;
		}
	} while (input);

	return 0;
}

接下来,我们需要对游戏内容进行具体地实现:

分析:我们需要一个数组来存放布置好的雷,我们用1表示雷,0表示非雷;而我们在排查雷的时候,如果该坐标不是雷,需要显示它周围有多少个雷,那么如果有一个雷,这里的1和表示是雷的1就会让人产生歧义,所以我们还需要一个数组来用来排查雷,这个数组一开始全部用‘*’表示,那么为了两个数组能使用同一个函数,存放布置好的雷的数组可以定义为字符数组,‘1’表示雷,‘0’表示非雷。在排查雷的时候,如果该坐标在最边上,那么它周围的八个坐标中有一部分越界了,所以我们可以在边界外再加上一圈。


  1. 初始化棋盘
代码语言:javascript复制
//game.h

#include <stdio.h>

#define ROW 9
#define COL 9

#define ROWS ROW   2
#define COLS COL   2

//初始化棋盘
void InitBoard(char board[ROWS][COLS], int rows, int cols, char set);
代码语言:javascript复制
//game.c

#include "game.h"

void InitBoard(char board[ROWS][COLS], int rows, int cols, char set)
{
	int i = 0;

	for (i = 0; i < rows; i  )
	{
		int j = 0;

		for (j = 0; j < cols; j  )
		{
			board[i][j] = set;
		}

	}
	
}
代码语言:javascript复制
//test.c

#include "game.h"

void game()
{
	char mine[ROWS][COLS];//存放布置好的雷
	char show[ROWS][COLS];//存放排查出的雷的信息
	//初始化棋盘
	//1. mine数组最开始是全'0'
	//2. show数组最开始是全'*'
	InitBoard(mine, ROWS, COLS, '0');
	InitBoard(show, ROWS, COLS, '*');
}

  1. 打印棋盘
代码语言:javascript复制
//game.h

#include <stdio.h>

#define ROW 9
#define COL 9

#define ROWS ROW   2
#define COLS COL   2

//打印棋盘
void DisplayBoard(char board[ROWS][COLS], int row, int col);
代码语言:javascript复制
//game.c

#include "game.h"

void DisplayBoard(char board[ROWS][COLS], int row, int col)
{
	int i = 0;
	printf("------扫雷游戏------n");

	for (i = 0; i <= col; 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");
	}

}
代码语言:javascript复制
//test.c

#include "game.h"

void game()
{
	char mine[ROWS][COLS];//存放布置好的雷
	char show[ROWS][COLS];//存放排查出的雷的信息
	//初始化棋盘
	//1. mine数组最开始是全'0'
	//2. show数组最开始是全'*'
	InitBoard(mine, ROWS, COLS, '0');
	InitBoard(show, ROWS, COLS, '*');
	//打印棋盘
	//DisplayBoard(mine, ROW, COL);
	DisplayBoard(show, ROW, COL);
}

  1. 布置雷
代码语言:javascript复制
//game.h

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define EASY_COUNT 10

#define ROW 9
#define COL 9

#define ROWS ROW   2
#define COLS COL   2

//布置雷
void SetMine(char board[ROWS][COLS], int row, int col);
代码语言:javascript复制
//game.c

#include "game.h"

void SetMine(char board[ROWS][COLS], int row, int col)
{
	//布置10个雷
	//生成随机的坐标,布置雷
	int count = EASY_COUNT;

	while (count)
	{
		int x = rand() % row   1;
		int y = rand() % col   1;

		if ('0' == board[x][y])
		{
			board[x][y] = '1';
			count--;
		}

	}

}
代码语言:javascript复制
//test.c

#include "game.h"

void game()
{
	char mine[ROWS][COLS];//存放布置好的雷
	char show[ROWS][COLS];//存放排查出的雷的信息
	//初始化棋盘
	//1. mine数组最开始是全'0'
	//2. show数组最开始是全'*'
	InitBoard(mine, ROWS, COLS, '0');
	InitBoard(show, ROWS, COLS, '*');
	//打印棋盘
	//DisplayBoard(mine, ROW, COL);
	DisplayBoard(show, ROW, COL);
	//1. 布置雷
	SetMine(mine, ROW, COL);
	//DisplayBoard(mine, ROW, COL);
}

int main()
{
	srand((unsigned int)time(NULL));

	return 0;
}

  1. 排查雷
代码语言:javascript复制
//game.h

#include <stdio.h>

#define EASY_COUNT 10

#define ROW 9
#define COL 9

#define ROWS ROW   2
#define COLS COL   2

//排查雷
void FindMine(char mine[ROWS][COLS], char show[ROWS][COLS], int row, int col);
代码语言:javascript复制
//game.c

#include "game.h"

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

void FindMine(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("请输入要排查的坐标:>");
		scanf("%d %d", &x, &y);

		if (x >= 1 && x <= row && y >= 1 && y <= col)
		{
			
			if ('1' == mine[x][y])
			{
				printf("很遗憾,你被炸死了n");
				DisplayBoard(mine, ROW, COL);
				break;
			}
			else
			{
				//该位置不是雷,就统计这个坐标周围有几个雷
				int count = GetMineCount(mine, x, y);
				show[x][y] = count   '0';
				DisplayBoard(show, ROW, COL);
				win  ;
			}

		}
		else
		{
			printf("坐标非法,重新输入n");
		}

	}

	if ((row * col - EASY_COUNT) == win)
	{
		printf("恭喜你,排雷成功n");
		DisplayBoard(mine, ROW, COL);
	}

}

那么,我们能不能做到输入一个坐标,如果不是雷的话,它就可以展开一片呢?

这是可以做到的,但是我们需要用到递归。

展开的条件:

  1. 该坐标不是雷
  2. 该坐标周围没有雷
  3. 该坐标没有被排查过
