Inheritance is the feature of OOPs that describes the reusability of code. There is no possibility that someone maintaining the code may inadvertently point to or otherwise access the wrong data . OO reuse is much the same as non-OO reuse. Explanation: The interaction between two object is called the message passing feature. when we want to create a new class and there is already a class that includes some of the code that we want, we can derive our new class from the existing class. One of the most important and essential features of object-oriented programming in C is data abstraction. It is also taught as a conventional method to write for the most part of a programmers school career. This concept is often used to hide the internal state representation of an object from the outside. For example, add(20,30) calls the two-parameter add() function, whereas add(10,20,30) calls the three-parameter add method. It makes the code reusability and makes the file lighter in weight with less number of lines of source code. b. Inheritance. In Python, class form the basis of OOP. b) Object must be used is violated These concepts of sighting the OOPS features correspondence in I look at OOP as more of a way to interact with objects and abstract away the details of the data structure. Method overloading signifies a method having the same name can exhibit multiple functionalities based on its parameters. d) Function Overriding Object-Oriented Security is the practice of using common object-oriented design patterns as a mechanism for access control. OBJECT-ORIENTED PROGRAMMING OBJECT-ORIENTED PROGRAMMING PROMOTES MODULARITY AND REUSE It is often "claimed" that object-oriented programming is a better way of writing more modular programs leverages code sharing and design reuse minimises maintenance costs Thanks to its abstraction mechanisms 10.
