One of the most practical examples of encapsulation is a school bag. Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or super class or base class in a subclass and in addition to that, adding extra more features or data members in the subclass or child class or derived class. A class is like a blueprint for creating objects. There are many ways to bypass encapsulation, and avoiding usage of questionable practices will help to keep it intact in both C and C++. Which feature of OOPS described the reusability of code? - Electrical Exams First of all, OOP way of code reuse is not the myth at all; the problem is different. Classes may also have functions known as methods that are exclusively accessible to objects of that kind. This feature is dependent on the programming language used. Because an object can only be associated with data in predefined classes or templates, the object can only "know" about the data it needs to know about. Answer: The 4 basic features are inheritance, polymorphism, encapsulation and abstraction. c) Data may/may not be declared using object If different properties and functions of a real world entity is grouped or embedded into a single element, what is it called in OOP language? OOPS is one of the most popular and useful programming technology. b) Polymorphism In procedural programming, a program is divided into various procedures or functions which operate on data, the issue with this approach is, when the program grows larger, the code redundancy, maintainability, and complexity increases.
