When you overload the > operators for a class, the overloaded function must be a friend function for that class. When a friend cannot be inherited, it cannot be used as a virtual function and cannot use polymorphism. You can use the following

usingSystem;usingSystem.Collections.Generic;usingSystem.Linq;usingSystem.Text;usingSystem.Net.Security;usingSystem.Security.Cryptography.X509Certificates;usingSystem.Net;usingSystem.IO;usingSystem.IO.Compression;usingSystem.Text.RegularExpressions;

Constructors can use the Base keyword to invoke the constructor of the base class. For example:public class Manager:employee{ Public Manager (int annualsalary) : Base (Annualsalary) { ADD further instructions here. }}In this

First, understand what is called polymorphism:The same operation acts on different objects, can have different interpretations, produce different execution results, which is polymorphism. To give an example of an image, when we listen to a concert,
