It doesn't have to re-create the same function again and again for different values but, it uses the same function to call different data types. As such, several jobs require candidates to have a profound understanding of C++. The imperative, object-oriented programming language is widely used as a general-purpose programming language. C++ is still as relevant today as it was during its advent in the mid-80s. Polymorphism: is a feature that deals with different values that can be used by only one function. Top 40 C++ Interview Questions and Answers in 2023.A child can inherit the properties of the parent and it remains helpful in creating a hierarchy in the system to keep things more modular. Inheritance: it deals with the relationship that exists between the parent and child classes.Encapsulation: it deals with the grouping of data and functions together at one place or it can be said in an object that defines the interface of their interaction and the relationship between them.The features that are being provided in object oriented programming is: What is object-oriented programming (OOP) Answer: 2.

Object oriented programming allows creating a modular approach to make it more abstract and create the interactions between them. Essential 54 OOP (Object Oriented Programming) interview questions and answers in 2021 1. Q 6) Explain Abstraction with a real-time example. Different functions have to be used to keep the code different from the data provided. This shows the relationship between different objects or in between the same objects.
