因此，我创建的程序允许用户登录到“工资申请”。用户名，密码和帐号已被硬编码，用户可以三次尝试登录。如果三次尝试失败，则程序将终止。如果用户成功登录，程序将继续运行并打开一个菜单。我遇到的问题是，一旦用户成功登录，程序将不会继续运行（不会打开菜单）。我可能错过了一些非常基本的东西，但我似乎无法找到在哪里我出错了。任何更正都表示赞赏。用户'登录'后程序将不会继续运行
菜单不完整，我只是试图使它在此刻正确运行。
感谢

你好，这伟大的工作，但原来你而提供的代码继续打开菜单三次连后，不正确的尝试经过三次不正确的登录尝试的程序终止。有没有办法让程序保持在三次不正确的登录尝试后终止，并且只有在成功登录后才能打开菜单。除此之外，它可以正常工作，谢谢。 – Yaz
好的，修好了！请点击绿色箭头“接受”答案，如果你现在对它感到满意:) – vikingsteve
