I need help with this C++ lab. Analyze the screenshot and identify all the objects. For each object, you need to implement the class definition (i.e. .h) and the class implementation (i.e. .cpp). You also need to define the member variables, mutator methods, accessor methods, constructor, destructor. I also provide an example.

Note: Question of Object-oriented programming
Encapsulation is one of the fundamental concepts in object-oriented programming. It is also often used to hide the internal representation or state of an object from outside. This is called information hiding. By using the data in Figure 1, show your investigation if hacker try to approach to gain access to the code of your bank account. class Account { private int account_number; private int account_balance; public void show Data() { //code to show data public void deposit(int a) { if (a < 0) { //show error } else account_balance = account_balance + a; Figure 1: Account class
Describe the classes, methods and attributes that you would use in the Object Oriented design of a simulated automobile. Use this format to describe your classes: Class: Door Methods: void Open(), void Close(), void SetLock(bool), bool GetLocked(), etc. Attributes: bool open, bool locked, class Window, etc.
There are notable differences between static and instance methods.
