класс — классы C ++ (состав и наследование — заголовочные файлы, массив классов)

Я написал 4 заголовочных файла (классов), из которых 3 класса были успешно скомпилированы (Customer, GoldCustomer и PlatinumCustomer). GoldCustomer и PlatinumCustomer являются деривацией (наследованием) Клиента, в то время как проблемный класс MovieTicket является составной частью всех трех других классов. Это должно следовать наложенному требованию: показать наследственность и состав.

Компиляция MovieTicket дает мне эти ошибки. Может ли кто-нибудь помочь изучить и объяснить? Кажется, что есть повторение объявления классов (но из того, что я прочитал в Google, пока вы включаете классы в заголовочные файлы и ставите охрану заголовка, эта ошибка не появится). Еще одна вещь, мой массив классов дает ошибки … Я понятия не имею, почему
