使用IF語句檢查數組輸入的問題

Question

void checkboard函數不起作用。這是一個tic tac腳趾遊戲。因此，如果有人贏得比賽或者是平局，那麼每次移動後該功能都會被檢查。在有人贏了或者有平局之後，董事會將被重新設置，並且遊戲將會開始。我無法讓無效的checkboard函數工作。請幫我解決這個問題。

檢查板應檢查每個用戶的輸入，看看該比賽是否贏了。所以checkboard必須檢查playerOne是否有一行或對角線的X，或者如果playerTwo有這種方式，或者有一條平手。如果玩家獲勝或者有抽籤，它會告訴誰贏了或者有一個平局，然後詢問用戶他們是否想再玩一次或退出該程序。從他們的迴應中，棋盤重置或遊戲退出。

我認爲問題在於無論如何，bGameOver一直保持真實。在gameover之前，我把代碼放在bGameOver = false之後，並且程序按照它的設想運行。所以一些if語句中的一些地方，在1次移動後，bGameOver = true。

解決問題後，我想提出一些建議，只有在問題得到解決後才能改進。

Answer 1

怎麼樣，如果你使用的簽名：

void checkboard(char** CurrentPlayer, char** squares, char &playerMarker, bool bGameOver,char playerOne[]); 

雖然我認爲這是不應該改變的唯一的事情，我會建議你讀多一點關於數組和指針，用較小的程序練習它。

我不知道你是如何編碼所有這些，而不會注意到它沒有按預期工作。

我也不知道是否有人會花時間爲你修復你的程序。這是作業。

Answer 2

if (board[0][0] = playerMarker) 

這將始終將playerMarker分配到板[0] [0]。你必須習慣「=」（賦值）和「==」（問題「這些是否相等？」）之間的區別。 Yoda Conditions雖然這不會幫助你在這裏。
