正在实现密码锁，但无法弄清楚如何实现旋钮

问题描述

所以从本质上讲，我正在尝试创建一个模拟密码锁的程序。

说明：在本作业中，要求您指定，设计，实现和测试可在模拟密码锁的程序中使用的类。锁有一个圆形旋钮，在边缘上标记了数字0到39，并且有一个三位数字的组合，我们将其称为x，y，z。要打开锁，您必须顺时针旋转旋钮至少整整一圈，并以x停在顶部；然后逆时针旋转旋钮，第二次停止y出现在顶部；最后再次顺时针旋转旋钮，下次z出现在顶部时停止。此时，您可以打开锁。您的锁类应具有一个初始化三位数组合的构造函数（默认参数使用0、0、0）。

还提供以下成员函数：

1. 将锁的密码更改为新的三位数密码。
2. 沿给定方向旋转旋钮，直到指定的数字出现在顶部。
3. 关闭锁。
4. 尝试打开锁。
5. 查询锁的状态（打开或关闭）。
6. 告诉您当前排名靠前的数字。

代码如下：

// Lock_Outline.cpp : This file contains a combination lock outline.
//
//CONSTRUCTORS for the Combo_Lock class:
//   Combo_Lock(int x = 0,int y = 0,int z = 0)
//      Precondition: All three lock sections must start at 0.
//      Postcondition: The lock must be able to be opened with the right combination.
//MODIFICATION MEMBER FUNCTIONS for the Combo_Lock class:
//   void AltCombo(int x,int y,int z)
//      Postcondition: These three values are able to be changed.
//   void TurnKnob(bool Dir,int NumClicks)
//      Postcondition: The direction and number for the 3 numbers must be able to be entered in.
//CONSTANT MEMBER FUNCTIONS for the Combo_Lock class:
//   GetLockStatus(()
//      Postcondition: The lock is either open or closed.
//   GetCurrentNumber()
//      Postcondition: The number turned to must be returned.
