In C++ I've run into yet another brick wall.  I have a class called arena
that is a 50x50 arena for obstacles and robots (for now anyway).  I'm
running into problems because I only want to have one copy of the arena and
multiple copies of the robots or whatever I want to put.

Would I do it something like this?

int robot::robot(arena arenacopy)
  {
   .
   .
   .
  }

int robot::robofunction(void)
  {
   arenacopy.arenafunction();
  }

Would this work?

Also I have an enum to define the objects in a buffer of the arena would it
be best to derive a class from arena and put all the enum and enum specific
(the ones that use the enums) functions there?

<TIA>
