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。
- 初始化棋盘
//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, '*');
}
- 打印棋盘
//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);
}
- 布置雷
//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;
}
- 排查雷
//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:
- 该坐标不是雷
- 该坐标周围没有雷
- 该坐标没有被排查过
