In C++ please.

Ticket class (Ticket.h)

Ticket class is an abstract class. Specify the following twofunctions as pure virtual functions.

• int getFinalPrice();
• string getTicketInfo();

Define the Ticket destructor. This destructor will output amessage

Ticket is expired.

MovieTicket class (MovieTicket.h /.cpp)

MovieTicket is derived from the Ticket class. Please declare thefollowing functions in the MovieTicket class (in MovieTicket.h) andprovide their implementations in (MovieTicket.cpp)

• int getFinalPrice(); This function will return the price on theticket plus a processing fee of $1
• string getTicketInfo(); This function will return a stringencoding the ticket information in the following format

Movie ticket for  at . Seat Info: Row , Column . Ticket price: $

Hint: use addition operator (+) to concatenate differentinformation into one string. Use to_string(int) to convert aninteger into a string.

• the destructor that outputs the following message

The movie ticket has been used.

ConcertTicket class (ConcertTicket.h /.cpp)

ConcertTicket is derived from the Ticket class. Please declarethe following functions in the ConcertTicket class (inConcertTicket.h) and provide their implementations in(ConcertTicket.cpp)

• int getFinalPrice(); This function will return the price on theticket plus a processing fee of $5
• string getTicketInfo(); This function will return a stringencoding the ticket information in the following format

Concert ticket for  at . Seat Info: Row , Column . Ticket price: $

• the destructor that outputs the following message

The concert ticket has been used.

TicketMaster class (TicketMaster.cpp)

The TicketMaster class consists of a list of Ticket pointers,tickets, that will be used to associate with either MovieTicketobjects or ConcertTicket objects. tickets is a static array withfixed size (MAX_SIZE=100). Complete the following functions.

• void purchaseTicket(Ticket *); This function will take a Ticketpointer that may pointer to either a MovieTicket object or aConcertTicket object as input. The function will then add thispointer to the tickets array and increase the ticketsSoldcount.

• void computeBoxOffice(); This function will call the respectivegetPrice() functions of the objects that the individual tickets'pointers are pointing to and compute the sum of the prices of thosesold tickets, then assign the total amount to the boxOffice membervariable.

main() function

The main is commented in the initial template to allow you totest the classes first (Test cases 1-5). After passing these testcases, uncomment and complete the main. Uncommentingthe main while your class is still incomplete will lead to compilererrors.

Main.cpp:

#include "TicketMaster.h"
#include "MovieTicket.h"
#include "ConcertTicket.h"

int main()
{
//TODO: uncomment the following if you complete allthe classes following the instruction
/*
TicketMaster tm;
Ticket *ticket = new MovieTicket("7PM on April 1,2021", 15, "Godzilla vs Kong", 5, 6);
tm.purchaseTicket(ticket);

ticket = new MovieTicket("5PM on May 28, 2021", 12,"Cruella", 6, 6);
tm.purchaseTicket(ticket);

ticket = new ConcertTicket("8PM on June 2, 2021", 120,"Imagine Dragon", 25, 18);
tm.purchaseTicket(ticket);

cout << "The information of sold tickets: "<< endl;
for (int i=0; i<3; i++)
cout <getTicketInfo() << endl;

cout << endl;

tm.computeBoxOffice();
cout << "The boxoffice is $" < */

return 0;
