我很無聊，所以我讓你的程序更好。這些都在一個文件中，但將其分解爲多個文件很容易。將每個類的成員和類定義分開，並將它們放在它們自己的文件中，然後將main放在它自己的文件中。
我做了幾件事情，可能會讓你覺得奇特。如果你看到的東西，問它在一個評論，我會解釋自己

此代碼顯示出你的原始版本沒有以下特點：
- 你可以贏得比賽
- 與windows掃雷一樣，在空的空間中間拾取一塊清除整個空間
- 輸入驗證
- 內存管理（您剛剛在堆棧上使用了內存，它沒有已經以新的和刪除任何
- 繼承
- 壓痕是否一致（不一致的縮進閱讀代碼是不好玩）
爲什麼「C」的標籤？ –
你應該結合newBoard和reDraw，因爲猜測是不同的。 newBoard沒有猜測。 –
@FredLarson我不確定C標籤是什麼 – metaDNA
