The main principles of object-oriented programming are abstraction, encapsulation, inheritance, and polymorphism. And finally the body of class. Specifically, the right hand. These objects can contain the data (attribute) and the methods (behavior), just like real-life entities that we model into our applications. However, the advantages of object-oriented programming are many. The class that provides its attributes is known as the base class and the class that accepts those attributes is known as a derived class. Methods and attributes that are available from outside the class are known as the public / external interface. Reusability in OOP is achieved by using C++ features that allow you to extend or reuse parent, super class, or base class properties in a subclass, as well as adding additional features or data members to the subclass, child class, or derived class. d) Abstraction Were expected to make two distinct sorts of polygons: a Rectangle and a Triangle. Inheritance is relevant due to the concept of Code Reusability. APL (A Programming Language) is a general-purpose, third-generation ( 3GL ) programming language that allows certain data manipulations to be expressed with a special non-ASCII set of symbols, resulting in programs that are shorter than would be possible using most other languages.
