What is Dynamic or run time polymorphism
The actual mean of polymorphism word is having many forms. Into OOPs(object-oriented programming) paradigm, polymorphism is often expressed as 'one interface, multiple functions'.
The technique of linking a function with an object during compile time is called early binding. This is also called static binding. C# provides two techniques to implement static polymorphism. They are −
C sharp allows you to create abstract classes that are used to provide partial class implementation of an interface. Where the Implementation is completed when a derived class inherits from it. Because, the AbstractClasses contain abstract methods, which are implemented by the derived class. So, the derived classes have more specialized functionality.
Here are the rules about abstract classes −
When a class is declared sealed, it cannot be inherited, abstract classes cannot be declared sealed.
