// 1.寫一個游戲菜單 Menu()

 // 1.初始化二維數(shù)組 Init_Interface()
 // 2.打印游戲界面 Print_Interface()
 // 3.玩家掀起指定位置 Play() --> 指定輸入坐標(biāo)（判斷合法性）
 // 1.判斷該位置是否是雷
 // 2.判斷是否掀掉所有空地
 // 3.如果掀開的是空地，則判斷該空地周圍是否有雷
  // 1.如果周圍有雷，則統(tǒng)計周圍雷的個數(shù)
  // 2.如果周圍沒有雷，則掀開周圍除了雷的所有空地，并且統(tǒng)計所掀開空地周圍雷的個數(shù)
 // 4.更新地圖
 // 5.繼續(xù) 3 的循環(huán)

//定義全局變量：
//定義掃雷地圖的長和寬
#define MAX_ROW 9
#define MAX_COL 9
//定義默認(rèn)的雷數(shù)
#define DEFAULT_MINE 9
//定義兩個二維數(shù)組，分別存放初始地圖和雷陣
