POLYMORPHISM is derived from two latin words poly(means-
many) and morphs(means-forms).this concept of OOPS provides
one function to be carried out in several ways or on
several object types.
working:-The polymorphism is the ability of responding
different object in there own way to a particular
message.so,when message is sent requesting an object to do
particular function,the message names the function the
object should perform.beacause diffrent objects can have
different functions with same name,the meaning of the
message must be decided with respect to the particular
object that recieved the message.so,the same message sent
to two different objects can invoke two different functions.

example:-If a brazilian is commanded to speak(),he/she may
speak portuguese. However, if a indian is commanded to speak
(), he/she may speak hindi. They both inherit speak() from
human, but their Subclass methods override the methods of
the Superclass; this is Overriding Polymorphism and
Inheritance. Adding a walk class to human would give both
indian and brazilian object's the same walk method.

// Assembly: Common Classes
// Namespace: CommonClasses

public interface Ihuman
{
string Name
{
get;
}
string Talk();
}

// Assembly: human
// Namespace: human

public class humanBase
{
private string _name;
AnimalBase(string name)
{
_name = name;
}
public string Name
{
get
{
return _name;
}
}
}

// Assembly: human
// Namespace: human

public class indian : humanBase, Ihuman
{
public indian(String name) :
base(name)
{
}

public string Talk() {
return "hindi!";
}
}

// Assembly: human
// Namespace: human

public class brazil : humanBase, Ihuman
{
public brazil(string name) :
base(name)
{
}

public string Talk() {
return "portuguese";
}
}

// Assembly: Program
// Namespace: Program
// References and Uses Assemblies: Common Classes, human

public class Testhuman
{
// prints the following:
//
// ram: hindi!
// Mr. harsh: hindi!
// Lara: portuguese!
//
public static void Main(String[] args)
{
List<Ihuman> human = new List<Ihuman>();
human.Add(new indian("ram"));
human.Add(new indian("Mr. harsh"));
human.Add(new brazilian("Lara"));

foreach(Ihuman human in human)
{
Console.WriteLine(human.Name + ": " +
human.Talk());
}
}
}

Question: Implement a base class Appointment and derived classes Onetime, Daily, Weekly, and Monthly. An appointment has a description (for example, “see the dentist”) and a date and time. Write a virtual function occurs_on(int year, int month, int day) that checks whether the appointment occurs on that date. For example, for a monthly appointment, you must check whether the day of the month matches. Then fill a vector of Appointment* with a mixture of appointments. Have the user enter a date and print out all appointments that happen on that date.
