Ввод С++ в структуру: _getch()

В С++ я пытаюсь ввести названия фильмов и годы выпуска и сохранить их в базе данных/структуре. Прежде чем я попрошу ввести названия и годы. У меня есть вход пользователя с учетными данными. В этом случае имя пользователя "ржавый" и пароль "ржавый".

Проблема, с которой я сталкиваюсь, заключается в том, что после проверки учетных данных первое название фильма для ввода в базу данных/структуру пропускается. Я считаю, что это как-то связано со мной, использующим функцию _getch, но я не совсем уверен.

Мой код ниже. Мой вывод выглядит так:

 Please enter your username
 rusty
 Please enter your password

 Access granted! Welcome rusty

 Enter title: Enter year: (input movie year)
 Enter title: (input movie title)
 Enter year: (input movie year)
 Enter title: (input movie title)
