![]() Inheritance is a property of object-oriented programming where a parent and child relationship is defined between two classes, allowing the child class to inherit the properties and methods of the parent class while also having the ability to define its own methods.Encapsulation and abstraction complement each other, with abstraction occurring during the design phase and encapsulation during the coding phase.Abstraction is a design process where public properties and methods are determined during the design phase, while encapsulation is implemented using access modifiers during the coding phase.The important pillars of object-oriented programming are abstraction, polymorphism, inheritance, and encapsulation, which can be remembered using the acronym APIE.Ībstraction and encapsulation are important in object-oriented programming, inheritance allows for parent-child relationships, the virtual keyword enables overriding in child classes, and method overloading and overriding have different uses in class structures.When giving answers in a technical interview, it is important to provide practical examples to support theoretical answers, such as using examples related to the domain you have worked in, rather than generic examples like cars and dogs.Object-oriented programming helps us think in terms of real-world objects, allowing for better code organization and management.Object-oriented programming is necessary because it improves code readability and has features like abstraction, encapsulation, and polymorphism, so it is important to answer interview questions about it directly and concisely. ![]() Share the video on social media to receive a free 200-page ebook on C# interview questions, and visit the website for more interview preparation resources.This video covers important object-oriented programming interview questions and answers, emphasizing the significance of understanding concepts such as abstraction, encapsulation, inheritance, polymorphism, and interfaces for successful interviews.Understanding object-oriented programming concepts like abstraction, encapsulation, inheritance, polymorphism, and interfaces is crucial for successful interviews, as it improves code readability and organization, and practical examples related to your domain are preferred over generic examples.
