本文将介绍如何用C语言多文件编程实现扫雷
该示例扫雷程序可实现以下几个功能:

• 自定义雷数
• 踩雷后会将所有雷显示出来
• 地图大小易修改
  

Mine_clearance.h

#pragma once#define _CRT_SECURE_NO_WARNINGS#include<stdio.h>#include<stdlib.h>#include<time.h>#define ROW 11#define COL 11#define 踩雷 0#define 玩家胜利 1int g_number_mine = (ROW - 1)*(COL - 1); //雷的数量上限char map[ROW][COL]; //玩家看到的地图char mine_map[ROW + 2][COL + 2]; //雷阵void Init_map(); //初始化玩家看到的地图void Init_mine_map(int input_count); //初始化雷阵void Print_map(); //打印地图void Print_mine_map(); //如果踩雷需要把雷阵打印出来void Player_move(int row, int col); //提示玩家输入坐标开始游戏 1.合法性校验(是否越界)2.是否重复输入,(已经输入过的)int Judge_mine_end(int row, int col); //判断是否踩雷char Count_number_mine(int row, int col); //统计周围八个方块雷的个数void Print_mine_number(int row, int col, int n);//将周围八个方块雷的数量显示在当前方块上int Judge_win(int input_count); //判断是否获胜
