I declare class 1. Class 2 is derived (publicly) from class 1. If I have a pointer to an instance of class 1, can I initialize it to the address of an instance of type class 2?
How is this dealt with when dealing with mulitple inheritance? Friend functions?
Yes, but unless you're using virtual methods you'll be using the class 2 object as a class 1 object (unless you cast).Quote:

You'll have to be more specific.
By that I meant, could I use the pointer if class 2 was derived from class 1, AND class 3 (multiple inheritance), and what if class 2 was declared as a friend of class 1 (the friend function thing).
Thanks for the help.
Yes, but it would still only be able to use class 1's interface as the class 1 pointer doesn't know anything about class 2 or 3. I'm not sure that declaring class 2 as a friend of class 1 would have any effect, but I'm don't know what you're trying to do.
