В трех ф-ях getaerodestination, getaerodeparture, getaerotype нужно вывести все рейсы к заданному пункту назначения, вывести типы самолетов по заданному пункту назначения и вывести все самолеты время прибытия которых позже заданного соответственно к каждой функции.
В этих строках :

3
| if (arr[i].get_destination == new_destination)
if (arr[i].get_destination == new_type)
if (arr[i].get_departure == new_departure) |
|
Выводит вот такие ошибки :

Ничего не могу понять, вроде char* с char* все правильно; потом, зачем-то конвертация с float в float пишет как ошибку.
Что посоветуете, какие замечания будут?
P.S. Как можно еще задать вот это все:
