What is the point of factory pattern?
The Factory Method design pattern is used by first defining a separate operation, a factory method, for creating an object, and then using this factory method by calling it to create the object. This enables writing of subclasses that decide how a parent object is created and what type of objects the parent contains.
What is the difference between class and object?
The difference is simple and conceptual. A class is a template for objects. … An object is a member or an “instance” of a class. An object has a state in which all of its properties have values that you either explicitly define or that are defined by default settings.

What is a factory in C++?
A factory method is a static method of a class that returns an object of that class’ type. But unlike a constructor, the actual object it returns might be an instance of a subclass. Another advantage of a factory method is that it can return existing instances multiple times.
