I'm having trouble making a copy constructor for this ListType class, the list type class implements the GeneralList interface, which is down below the ListType class.

I have to create a copy constructor that accepts a reference to another GeneralList Object.

Here is the ListType class


And here is the GeneralList interface

Here is what I have come up with, but it does not work.
Could someone help me understand why this copy constructor does not work, and how to modify it so that it does work?


Thanks for any help, it's much appreciated.


Thanks in advance.

Hi Andrew,

In the copy constructor, you are not setting the value of the number of elements. Although the "list" array has the right values, elements is still = 0.
