Which of the following is part of object-oriented programming practice?

Inheritance is a fundamental concept in object-oriented programming (OOP) that allows a class (often referred to as a child or subclass) to inherit properties and behaviors (methods) from another class (called a parent or superclass). This practice promotes code reusability and establishes a hierarchical relationship between classes, making it easier to manage and extend code. By inheriting attributes and methods, developers can create new classes that retain the functionality of existing ones while introducing new features or modifications.

In contrast, iteration (in the context of loops), function overloading (defining multiple functions with the same name but different parameters), and variable initialization (the process of assigning an initial value to a variable) are programming concepts that can exist independently of OOP. While they are important programming techniques and used in various programming paradigms, they don’t specifically define the OOP approach like inheritance does.
