to draw themselves, the draw function would

most likely be declared:

private

protected

virtual

friend

In the realm of object-oriented programming, particularly with C++, the draw function is often declared as virtual when creating a base class for shapes or graphical objects. This compels derived classes to implement their own specific versions of the function, allowing for dynamic binding and polymorphism when objects are accessed through base class pointers.

Another clever approach is to declare draw as protected. This enables subclasses to access and implement the function while preventing it from being called on instances of the base class, making it a great way to enforce the use of abstraction and encapsulation in creating more secure and robust code.
