C# Inheritance: Interview Questions and Concepts Explained

This video explains inheritance in C# by answering seven common interview questions (0:03). Inheritance is a key concept in object-oriented programming (OOP) that allows a class to inherit properties and methods from another class (0:05). Here are the key takeaways from the video: Base Class: The base class is the class from which other classes inherit (0:14). Access Modifier: The protected access modifier allows a derived class to access members of the base class (0:23). Method Overriding: To override a method in a derived class, you use the override keyword, and the base class method must be marked as virtual or abstract (0:36). Purpose of Overriding: Method overriding allows a derived class to provide a specific implementation of a method already defined in its base class (0:51). Inheritance Example: In a scenario where Animal is the base class and Dog is the derived class, Dog inherits all public and protected properties and methods from Animal (1:03). Preventing Inheritance: The sealed keyword is used in C# to prevent a class from being inherited (1:18).
