C语言实现扫雷

    C语言实现扫雷游戏，代码包括头文件声明定义，头文件实现，能够实现随机生成20个位置作为地雷位置，用户输入[1~10]区间，显示该位置周围雷的数量，当用户输入位置已有地雷或者当只剩20个位置时判定程序结束。

代码思路，创建两个二维数组，一个作为雷区，一个作为显示区，雷区只在程序结束时显示。每次用户操作后刷新显示区的数组成员。创建雷区二维数组12*12，显示区二维数组10*10，用‘0’代表安全区，‘1’代表雷区。

雷区的数组长度设定比显示区的数组长度多2，方便边框区域计算周围地雷数量。

头文件声明

#include <stdio.h>
#include <string.h>
#include <time.h>
#include <windows.h>

#define ROW 12 //10 + 2
#define COL 12
#define TOTAL 10*10
#define MINE_NUM 20

#pragma warning(disable:4996)

void SetMine(char mine[][COL], int row, int col);
void ShowBoard(char board[][COL], int row, int col);
char GetMines(char mine[][COL], int row, int col);
void Game();
void expand(char mine[][COL], int row, int col, char show);

头文件实现

#include "mine.h"

	return rand() % (end - start + 1) + start;
}

	srand((unsigned long)time(NULL));
	int count = 0;
	while (count < MINE_NUM){
		int x = GetRandIndex(1, 10);
		int y = GetRandIndex(1, 10);
		if (mine[x][y] == '0'){
			mine[x][y] = '1';

	}

void ShowBoard(char board[][COL], int row, int col)

void Game()
{

	char board[ROW][COL]; //show
	memset(mine, '0', sizeof(mine));
	memset(board, '*', sizeof(board));

主函数

#include "mine.h"

void Menu()
{
	printf("###################################\n");
	printf("## 1. Play               2. Exit ##\n");
	printf("###################################\n");
	printf("Please Select: ");
}
int main()
{
	int quit = 0;
	int select = 0;
	while (!quit){
		Menu();
		scanf("%d", &select);
		switch (select)
		{
		case 1:
			Game();
			break;
		case 2:
			printf("拜拜！\n");
			quit = 1;
			break;
		default:
			printf("选择错误，请重新选择！\n");
			break;
		}
	}
	system("pause");
	return 0;
}

这里用递归调用函数的方式来实现周围无地雷时向外展开

void expand(char board[][COL],char mine[][COL], int row, int col,char show){
	if (show == '0'){
		board[row][col] = show;
		expand(board, mine, row - 1, col - 1, GetMines(mine, row - 1, col - 1));
		expand(board, mine, row - 1, col, GetMines(mine, row - 1, col));
		expand(board, mine, row - 1, col + 1, GetMines(mine, row - 1, col + 1));
		expand(board, mine, row, col - 1, GetMines(mine, row, col - 1));
		expand(board, mine, row, col + 1, GetMines(mine, row, col + 1));
		expand(board, mine, row + 1, col - 1, GetMines(mine, row + 1, col - 1));
		expand(board, mine, row + 1, col, GetMines(mine, row + 1, col));
		expand(board, mine, row + 1, col + 1, GetMines(mine, row + 1, col + 1));
	}
	else{
		board[row][col] = show;
	}
}
