基于c++控制台的扫雷游戏

Screen   类用于与控制台交互

gotoxy(short x, short y)跳转到控制台的指定位置

void Init() 获取控制台 句柄

bool changeColor(WORD color)变更颜色

　　SL扫雷类

Init()初始化窗口高度宽度和类的数量，生成表格

InitTable() 有雷的地方值为-1，其它为周边雷的个数

DrawIn() 画窗口内部格子

DrawOut()画窗口边框

Run()运行游戏

bfs(int h,int w)对于值为0的格子，宽度搜索其周边的格子直到非0

show(int h,int w)当用户点击单击位置h,w 时被调用
