In Object-Oriented Programming (OOP), inheritance hierarchy refers to the structure in which classes inherit properties and methods from parent classes. It enables code reuse and organization. The hierarchy can have multiple levels, with subclasses inheriting from superclasses, forming a tree-like structure that promotes modular and maintainable code. https://www.knockinglive.com/exploring-the-layers-of-inheritance-hierarchy-in-oop/?snax_post_submission=success
