二维数组——扫雷

1.扫雷头文件(game.h):

#define _CRT_SECURE_NO_WARNINGS 1
#ifndef _GAME_H_
#define _GAME_H_
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW   10  //棋盘行
#define COL   10  //棋盘列
#define ROWS  12  //内部运行行
#define COLS  12  //内部运行列
#define MINE_NUM 20  //地雷数量
void menu();  //打印菜单
void game();  //开始游戏
void Show(char board[][ROWS], int row, int col);  //打印棋盘
void InitBoard(char board[][COLS], char mine[][COLS], int row, int col);  //棋盘初始化
void SetMine(char mine[][COLS], int row, int col, int num);  //设置雷
int FindMine(char mine[][ROWS], char board[][ROWS]);  //扫雷
int GetMineCount(char mine[][ROWS], int row, int col);  //计算附近雷数量
int Set_Assist(int i, int arr[], int brr[], int x, int y);  //设置雷的辅助函数
#endif

2.扫雷函数(game.c):

#include "game.h"
int row = 0, col = 0;
void menu()  //打印菜单
{
	printf("**********************\n");
	printf("********1 play********\n");
	printf("********0 exit********\n");
	printf("**********************\n");
}
void game()  //开始游戏
{
	int result=0,num=0;
	char board[ROWS][COLS] = { 0 };
	char mine[ROWS][COLS] = { 0 };
	InitBoard(board, mine, ROWS, COLS);  
	SetMine(mine, ROW, COL, MINE_NUM);
	while (1)
	{
		Show(board, ROW, COL);
		result=FindMine(mine, board);
		if (result == 1)
		{
			break;
		}
		else
		{
			num=GetMineCount(mine, row, col);
			board[row][col] = num+'0';  //字符1-字符0=数字1
		}
	}
	if (result == 1)
	{
		printf("你被炸死了\n");
		Show(board, ROW, COL);
	}
}
void InitBoard(char board[][COLS],char mine[][COLS],int row,int col)  //棋盘初始化
{
	int i = 0 ,j = 0;
	for (i = 0; i < row; i++)
	{
		for (j = 0; j < col; j++)
		{
			board[i][j] = '*';
			mine[i][j] = '*';
		}
	}

}
void Show(char board[][ROWS],int row,int col)  打印棋盘
{
	int i = 1, j = 1;
	for (i=1; i <= row; i++)
	{
		for (j=1; j <= col; j++)
		{
			printf("%-3c", board[i][j]);
		}
		printf("\n");
	}
}
void SetMine( char mine[][COLS], int row, int col, int num)  //设置雷
{
	int x = 0, y = 0, count = 0;
	int i = 1, arr[100], brr[100];
	srand((unsigned int)time(NULL));  //随机分布设置的雷
	x = rand() % ROW + 1;
	y = rand() % COL + 1;
	mine[x][y] = 'X';
	arr[0] = x, brr[0] = y;  //保证设置的雷不会重叠
	while (i < num)
	{
		do
		{
			x = rand() % ROW + 1;
			y = rand() % COL + 1;
		} while (count=Set_Assist( i,arr, brr, x,y));  //for (i=0;i<i;i++) if arr[i]==x&&brr[i]=y;return 1;break;
		mine[x][y] = 'X';
		arr[i] = x; brr[i] = y;
		i++;
	}
}
int GetMineCount(char mine[][ROWS], int x, int y)  //计算附近雷数量
{
	int count = 0;
	int i = x + 1, j = y + 1;
	for (x = x - 1; x<=i; x++)
	{
		for (y = y - 1; y <=j; y++)
		{
			if (mine[x][y] == 'X')
			{
				count++;
			}
		}
	}
	return count ;
}
int FindMine(char mine[][ROWS],char board[][ROWS] )  //扫雷
{
		int count = 0;
		printf("请输入坐标：");
		scanf("%d%d", &row,&col);
		if (mine[row][col] == 'X')
		{
			board[row][col] = 'X';
			return 1;
		}
		else
		{
			return 0;
		}
}
int Set_Assist(int i,int arr[],int brr[],int x,int y)   //设置雷的辅助函数
{
	int j = 0;
	for (j = 0; j < i; j++)
	{
		if (arr[j] == x&&brr[j] == y)
		{
			return 1;
			break;
		}
    }
	return 0;
}

3.扫雷主函数(main.c)：

#include "game.c"
int main()
{
	int input ;
	do
	{
		menu();
		scanf("%d", &input);
		switch (input)
		{
		case 1:
			printf("游戏开始了\n");
			game();  //进入游戏函数
			break;
		case 0:
			printf("感谢使用\n");
			break;
		default:
			printf("请输入正确的指令\n");
		}
	} while (input);  //输入0时为假，跳出循环退出程序
}
