Here's a probably quite stupid question but I'm still learning...

>From what I've understood, the main reason for using pointers in C++ is that
it allows pass-by-reference function calls. So, if you in a class have a
large member object that you know you will never pass around as a parameter,
would it be pointless to make this a pointer?

An example:

class A {
  private:
    B arrayOfBs[100];
}

If I know that I will never pass arrayOfBs around, is there any reason to
make the above a pointer to the array instead of as here, allocating the
whole thing on the stack?

Thanks,
Erik
