因此，我創建的程序允許用戶登錄到「工資申請」。用戶名，密碼和帳號已被硬編碼，用戶可以三次嘗試登錄。如果三次嘗試失敗，則程序將終止。如果用戶成功登錄，程序將繼續運行並打開一個菜單。我遇到的問題是，一旦用戶成功登錄，程序將不會繼續運行（不會打開菜單）。我可能錯過了一些非常基本的東西，但我似乎無法找到在哪裏我出錯了。任何更正都表示讚賞。用戶'登錄'後程序將不會繼續運行
菜單不完整，我只是試圖使它在此刻正確運行。
感謝

你好，這偉大的工作，但原來你而提供的代碼繼續打開菜單三次連後，不正確的嘗試經過三次不正確的登錄嘗試的程序終止。有沒有辦法讓程序保持在三次不正確的登錄嘗試後終止，並且只有在成功登錄後才能打開菜單。除此之外，它可以正常工作，謝謝。 – Yaz
好的，修好了！請點擊綠色箭頭「接受」答案，如果你現在對它感到滿意:) – vikingsteve
真棒謝謝你:) – Yaz
