Answer 1

Hello, I have a solution for you. Implemented everything as per the requirements. Defined following things in this answer.

1. Created a class Movie with title, and total earnings.
2. Created a class Theatre with currently running movie, total seats capacity, and number of seats sold.
3. Created a class Ticket which contains the Theatre object where the ticket is valid.
4. Created a Patron class with age and Ticket
5. Appropriate constructors are defined to each classes.
6. Used the TestProgram given in the question and verified the output.
7. Comments are included, If you have any doubts, feel free to ask, Thanks
