Error C2100

Alright I'm having problem with this program where I have three different classes but the functions don't seem to be working because of it being a pointer or I'm doing something wrong

You have too many "dereferences" on lines 112 and 118.

ships[index] is a Ship*.
Therefore *ship[index] is a Ship.
Ship does not overload the member operator (->).

Get rid of the initial *.

Also, you would be wise to add a virtual destructor in Ship.

Well it needs to be a array of Ship pointers where the array elements should be initialized with the address of dynamically allocated objects of the three classes.

I can understand the virtual destructor part

After playing around with it for a while I got it to work, but it's not quite as versatile as I originally wanted, but it works for its purpose. Thanks for the help.
