A theatre sells seats for shows and needs a system to keep track of the seats they have sold tickets for. Define a class for a type called ShowTicket. The class should contain fields for the row, seat number, and whether the ticket has been sold or not. Define a constructor which accepts as arguments the row and seat number and sets the sold status to false in the constructor initialization section. Include member functions to check if the ticket has been sold; to update the ticket status to sold; and to print the row, seat number, and sold status. Embed your class definition in a test program which creates some ShowTicket objects, sets some tickets as sold, and prints each of them out.
