Tic-tac-toe prog

Question

最後に私が望むものがわからない。このTic-tac-toeが私を殺しています。エラーがコードブロックに応じて「}」の最後の4である：

} 

エラーが正しい「リターン（0）;}」の後に発生するライン、と私は何をする他に何かわかりません。

Answer 1

あなたのwhile条件は：

while (!GameOverDecider) { 
    if (Option == 2) { 
     cout << "Ok....." << endl; 
    } 
    return (0); 
    } 

これはdo内にあり、一度それがしばらくので、エラーを取得することはできません終了します。下にある4つの括弧の中の1つの括弧を減らし、この間に1つの括弧を追加します。あなたはdo {を持って

if (Option == 1) { 

後行で

Answer 2

。しかし、そのブロックの最後にはwhileまたはuntilという条件はありません。それは

do { 
    ... 
} while (!GameOverDecider); 

する必要があり、その誤ったwhileループ内のコードが側にそれてはならないように、それは最初ifと同じレベルにする必要がありそうです。
