The size data member is assigned numEvents. The events data member has its elements assigned to be nullptr. setEvents: This function takes in an int variable s and an Event* const array named newEvents. Assign s to size. Copy the elements from newEvents to our events array. Each element of the events array must be assigned new addresses before copying the newEvents element's events. You should check what other's event element type is to properly assign a new address for either Birthday or Concert. Since the newEvents array is an Event* const array, you must cast the dereferenced element into either a Birthday or Concert reference when copying from newEvents' array. Destructor The destructor must free up the memory that the pointers have used. Hint: You must loop through the events array and delete each element as each element is a pointer. Make sure they are not nullptr before deleting. Copy Constructor: you must do a memberwise copy of of size, numBd, numC, time, and date. Finally, you may use the setEvents function to initialize the events array. Copy Assignment Operator: similar to the copy constructor, make sure to assign events based on their type. eventsFromInput: this function is provided for you. This function is what will be getting the event information from standard input. They are not ordered by time or date.
