Explain interface Interface in C# is a blueprint of a class. It is like abstract class because all the methods which are declared inside the interface are abstract methods. It cannot have method body and cannot be instantiated. It is used  to achieve multiple inheritance  which can't be achieved by class. It is used  to achieve fully abstraction  because it cannot have method body. Its implementation must be provided by class or struct. The class or struct which implements the interface, must provide the implementation of all the methods declared inside the interface. Example using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; interface IStudent {     int subtotal(int s1, int s2, int s3, int s4);     float per(int total);     string grade(float per);       } class Customer : IStudent {         public ...

What is Abstrect class An abstract class is a special type of class that cannot be instantiated. An abstract class is designed to be inherited by sub classes that either implement or override its methods. In other words, abstract classes are either partially implemented or not implemented at all. You can have functionality in your abstract class—the methods in an abstract class can be both abstract and concrete. An abstract class can have constructors—this is one major difference between an abstract class and an interface. You can take advantage of abstract classes to design components and specify some level of common functionality that must be implemented by derived classes.  Code of Abstrect class example  using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace abstrectClass {     abstract class person     {         public stri...
