Мне нужна помощь в поиске того, что вызывает ошибку.

---

В BankAccountMain.cpp не может быть изменено из-за ограничений назначения.

Я получаю ошибку C2039: 'setInterestRate' : не является членом 'SavingsAccount' и ошибку C2039: 'getNumberOfDays' : не является членом 'SavingsAccount'

Вот мои коды для 2 файлов, которые появляются
