![]() ![]() The computation will be very different for a Rectangle subclass (width * height) than for the Circle subclass (pi * radius2). In computer programming, Inheritance is one of the most important concepts followed by Abstraction, Encapsulation and Polymorphism in the Object Oriented. But the trouble is that the Shape class cannot provide the actual implementation of such operations, because Shape is too abstract and doesn’t “know” how to calculate, say its own area. This class could provide many more useful operations, such as area() (to let the shape compute its own area) or draw() (to let the shape draw itself on the screen), etc. This is the second article in the series of articles related to. Inheritance: allowing code to be reused between related types. In this article, we will cover the various types of inheritance in Python OOPs. ![]() Īs an example of how virtual functions could be useful, consider again the Shape class introduced before. The four main pillars of Object Oriented Programming are Inheritance, Polymorphism, Encapsulation, and Data Abstraction, of which Inheritance is one of the most important aspects of the OOPs concept. The implementation presented here (and used in the QP/C real-time framework) has very similar performance and memory overhead as virtual functions in C++. In C, you can also implement virtual functions in a number of ways. Composition involves using other classes to build more complex classes. C++ implements polymorphism with virtual functions. Like Inheritance, Composition is a concept in object-oriented programming that models the relationship between two classes. Super Class:The class whose properties are inherited. Sub Class: The class that inherits properties from another class is called Sub class or Derived Class. Multiple inheritance does not mean that multiple subclasses share the same superclass. Inheritance is one of the most important features of Object-Oriented Programming. One important object-oriented mechanism is multiple inheritance. Polymorphism is the ability to substitute objects of matching interfaces for one another at run-time. The capability of a class to derive properties and characteristics from another class is called Inheritance. ![]()
