C语言实现扫雷游戏

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

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
