Let's enumerate the elements involved in Generalization of object factories. This gives us the intellectual workout necessary for putting together a generic object factory.• Concrete product. A factory delivers some product in the form of an object.• Abstract product. Products inherit a base type (in our example, Shape). A product is an object whose type belongs to a hierarchy. The base type of the hierarchy is the abstract product. The factory behaves polymorphically in the sense that it returns a pointer to the abstract product,without conveying knowledge of the concrete product type.• Product type identifier. This is the object that identifies the type of the concrete product. As discussed, you have to have a type identifier to create a product because of the static C++ type system.• Product creator. The function or functor is specialized for creating exactly one type of object. We modeled the product creator using a pointer to function.
Class A is the highest level, while classes B and C are subcategories of it. Hence, although B and C share certain features and procedures, their respective implementations of many of those procedures are substantially distinct. Infer if A is a concrete class, abstract class, or interface.

Why is it required to invest more time and code in object-oriented programming to avoid classes from being needlessly connected? Your disposition is determined by three primary variables.
Abstract classes and interfaces may both be used to accomplish the goal of defining the behaviour of common objects.Which factors should you take into account when deciding whether to utilise an interface or an abstract class?
Why does avoiding classes that are needlessly connected require more work and writing of code in object-oriented programming? What are your position's three primary justifications?
Consider the scenario of a Pharmacy Management System. The following UML Class diagram shows a hierarchy of some of the classes in the system. (Shown in Picture) The StateManager Interface is a generic interface which has two methods changeState (boolean : status). This method is used to change the status of InvoiceItem and PrescriptionItem. The possible status for InvoiceItem can be (Available – true or Unavailable - false), whereas PrescriptionItem has status (Recommended-true or Prohibited – false) passed to the method as an argument. The reset () method sets the default value for both InvoiceItem and PrescriptionItem. The Item class is self-explanatory. It implements the StateManager interface, and has toString method which prints the information in the following format. "Item Name: <<name>> (<<id>>)” e.g. Item Name: Panadol (223) Two classes PrescriptionItem and InvoiceItem are inherited from Item class representing the items that can be sold with…
