It works in my project now which i'm writing since 2 days, i implemented all the methods my teacher wanted except that Is_Empty(), because first my Size was Positive not a Natural so i couldn't create empty strings, then i didn't know that my discriminant was bad, but now it works. The Error i wrote before was in a test project which i created only to examine the above problems separately, but in my main project it works fine at last. If you're curious i can copy the codes, but everything's okay now, thanks to you! Have a nice evening mate! :)
