Hello I am new to this forum although I have used this site for some time.
I'm studying OOP and I need some help because I got stuck with the following task.
The code consists of several classes so I send it as attached file.
The problem is described in detail in document "READ" in MP2 file.
I do not expect to someone solve my task just some advice or clue
where I made a mistake.
Thank you in advance.
