# include<iostream.h>

//using namespace std;

# define PI 3.142;

int main ()

{

int Rad,Height;

double area;


cout<<"Enter the radius;";

cin>>Rad;

cout<<"Enter the Height;";

cin>>Height;

area = 3.142 * Rad * Rad * Height;

cout<<"Radius="<<Rad<<endl;

cout<<"Height="<<Height<<endl;

cout<<"The Area of the circle is"<<area<<"\n";

return 0;

Question 1: 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. *This Should Be Done IN C++
