Question

Do that with C++ and please add more comment that make it understandable

In this hormework, you will implement a simple caledar application The implernentation shauld include a class narned Calendar, an abstract class named Event and two concrete classes narmed Task and Appointment which irherit from the Evernt class. The Event Class This will be an abstract class. It will have four private integer members called year, month, day and hour which desigate the tirne of the event. It shauld also have ar integer member called id which should be a unique id for the event. The id should start from zero and should incrernent by 1 for each new event generated. The event class should have a constructor that sets the evet tie (year, month, day and hour mernbers) and should also have get methods for its private mermbers. The event class will have a pure irtual function called print with the following prototype: virtual void printO const; The Task Class This class will derive fror the Event class. On top of the base class, it should have an extra private string mernber called taskname which includes the task to be performed. It should have a constructor, and set/get methods for its private member. Its print function should the print function of Event class which shauld print the tasknarne and event tirme irn the following format: Task with id 20 at 22/04/2019, 23:00: Submit CP homework 1 The Appointment Class This class will derive frorm the Event class. On top of the base class, it should have an extra private string merber clled personnarne with whorn the appointment is and a private string member place where the appointment ll be. It should have a constructor and set/get methods for its private members. Its prit function should iriplernent the print function of Event class which should print the appointment details in the following format: Appointment with id 21 at 16/04/2019,18:00: Dr. George Wilson, Marnara University The Calendar Class This class will be a container class for the Event objects. It will implement a linked list where each list elerment can be one of Task or Appointrment objects. It should have the following methods Event addEventnt eventType, t year, kt month, int day,int hur Alocates a new event object, azes it and ados the event to the end of the inkedist. t returns a pointer to the alocated event. eventTyoe is for a Task and 1 for an Appointment. deleteEventfint id); Remaves the event with the given id from the ist and deallocates the event object. void listEvents: Lists the events in the ist For each event in the list event should cal the oin function for that void filterEvents int year, int month Lists the events that are scheduled in the gven yearand month. For each event, it shouid a the print function for that event. The main function Implement a main function that does the following: 7. Adds 5 Task Events and 5 Appointment Events with various times to the calendar. Set the Task and Appointment details as you wisth. 2. Lists all events in the calendar. 3. Deletes an appointment you wish from the calendar. 4. Filters and lists all events scheduled at a certain day you designate.
