What is Inheritance, how does it work in C++?
Tutorial Details:
C and Cpp Inheritance
The ability to use the object-oriented programming is an important feature of C++. Lesson 12 introduced the idea of the class; if you have not read it and do not know the basic details of classes, you should read it before continuing this tutorial. This tutorial is n Inheritance is an important feature of classes; in fact, it is integral to the idea of object oriented programming.
Inheritance allows you to create a hierarchy of classes, with various classes of more specific natures inheriting the general aspects of more generalized classes. In this way, it is possible to structure a program starting with abstract ideas that are then implemented by specific classes. For example, you might have a class Animal from which class dog and cat inherent the traits that are general to all animals; at the same time, each of those classes will have attributes specific to the animal dog or cat.
Inheritence offers many useful features to programmers. The ability, for example, of a variable of a more general class to function as any of the more specific classes which inherit from it, called polymorphism, is handy. For now, we will concentrate on the basic syntax of inheritance. Polymorphism will be covered in its own tutorial.
Any class can inherit from any other class, but it is not necessarily good practice to use inheritance (put it in the bank rather than go on a vacation). Inheritance should be used when you have a more general class of objects that describes a set of objects.
