Top Features of OOPS - InterviewBit This mechanism actually inherits the fields and methods of the superclass. It can be best explained with an example with a comparison to C language; in C language there was one limitation that we can not use the already used function name, but C++ provides us a new feature of Polymorphism, by which we can use the same function name again and again with different signatures. These are achieved through Encapsulation, abstraction, inheritance, and polymorphism. For example, add(20,30) calls the two-parameter add() function, whereas add(10,20,30) calls the three-parameter add method. Encapsulation and abstraction are meant to hide/group data into one element. A prototype object serves as a base from which another object may derive its features and actions. 9) Which feature of OOPS described the reusability of code? Reusability in OOP achieves through the features of C++ where it possible to extend or reuse the properties of parent class or superclass 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.This whole set of mechanism is known as Inheritance. why is reusability important in ooad. D Abstraction. Code reuse may not be exactly what people think. Inheritance: This makes coding more flexible, which tends to lead to better code organization in smaller and simple units.
