Inheritance is the mechanism of basing an object or class upon another object (prototype-based inheritance) or class (class-based inheritance), retaining similar implementation. Also defined as deriving new classes (sub classes) from existing ones such as super class or base class and then forming them into a ______. In most class-based object-oriented languages like C++, an object created through inheritance, a "child object", acquires all the properties and behaviors of the "parent object", with the exception of: constructors, destructors, overloaded operators and friend functions of the base class. Inheritance allows programmers to create classes that are built upon existing classes, to specify a new implementation while maintaining the same behaviors (realizing an interface), to reuse code and to independently extend original software via public classes and interfaces. The relationships of objects or classes through inheritance give rise to a ______
hierarchy of classes

Study Notes
Inheritance in Object-Oriented Programming
- Inheritance is a mechanism that allows an object or class to be based on another object or class, retaining similar implementation.
- There are two types of inheritance: prototype-based inheritance and class-based inheritance.
- In class-based inheritance, new classes (subclasses) are derived from existing ones (super class or base class), forming a hierarchy of classes.
Characteristics of Inheritance
- A child object acquires all the properties and behaviors of the parent object, except for: • Constructors • Destructors • Overloaded operators • Friend functions of the base class
Benefits of Inheritance
- Allows programmers to create classes that are built upon existing classes.
- Enables specifying a new implementation while maintaining the same behaviors (realizing an interface).
- Facilitates code reuse.
- Enables independent extension of original software via public classes and interfaces.
