What is the difference between Virtual method and Abstract method?

Here is the difference between virtual methods and abstract methods in C#:

Virtual Methods

• Virtual methods are implemented in a base class and can be overridden in derived classes.
• The base class implementation provides a default behavior that can be used if a derived class does not override the method.
• If a derived class overrides a virtual method, it provides its own implementation that replaces the inherited implementation.
• Virtual methods allow for polymorphism, where objects of a derived class can be treated as objects of the base class and the correct method is called at runtime based on the actual type of the object.
• The virtual keyword is used to mark a method as virtual in the base class.
• The override keyword is used to override a virtual method in a derived class.

Abstract Methods

• Abstract methods are declared in an abstract base class but hav...
