The so-called factory function means that these built-in functions are all class objects. When you call them, you actually create a class instance."

When called, a class instance is actually created, that is, an object is first created using the class, and then the object is returned. The created functions all have the same attributes.

Course Introduction:C++ static functions can be used to implement the factory method pattern, which defines an interface for creating objects and defers the creation logic to subclasses. In C++, the factory method pattern can be implemented using static functions. These functions do not require instantiation of the class and can easily create objects of different types. Factory method pattern helps separate object creation logic and concrete shape classes, allows dynamic creation of objects, and provides extensibility so that new shape types can be easily added in the future.
