How to write a program that Concert Promoter.

Consider a class ConcertPromoter that records the tickets sold for a performance. Before the day of the concert, tickets are sold only over the phone. Sales on the day of the performance are made only in person at the concert venue. The class has the following attributes:

The name of the band

The capacity of the venue

The number of tickets sold

The price of a ticket sold by phone

The price of a ticket sold at the concert venue

The total sales amount

Whether sales are currently made by phone or at venue

It has the following methods:

Constructor

Record the sale of one of more tickets

Change from phone sales to sales at the concert venue

Return the number of tickets sold

Return the number of tickets remaining

Return the total sales from the concert

All other methods used by your class should be declared as private. You can make any additional private methods that you like.

(a) Implement the above class, making sure to comment each method in your class.

(b) Write a program using the ConcertPromoter class you wrote that will be used to record sales for a concert. Your program should record phone sales, then sales at the venue. As tickets are sold, the number of seats remaining should be displayed. At the end of the program, display the number of tickets sold and the total sales amount for the concert.
