Задача за за C# графичния интерфейс направен на WinFoms
A sport club has items in stock. Members of the club can borrow some items and later return them. You are tasked to make an application that manages the renting of these items. With this app it must be possible to register how many items are rented. We do not register who rented them, we only want to know how many are in stock and how many are rented.
