I'm about halfway up the c++ learning curve and I've run across a "how
do you..."  problem.  I have a class that looks like:

class class_a
  {
    static int a_var;
    int b_var;

    member functions...
  }

As I understand it, all objects of class_a will share a_var, and b_var
will be local to each object.  In my case, I am interested in b_var's
value relative to a_var for each object.  

This works fine except that now, it turns out, I need another set of
objects that do the exact same thing, except with a different a_var.
The only way I've been able to do this, has been to copy class_a and
rename it.  I would much rather do this by using class_a as the source
for both.  It seems I would need to form two subclasses or derived
classes of class_a that don't share a_var.  I haven't been able to do
this, nor have I been able to think of another alternative.  If anyone
knows a solution, I would be much obliged if they filled me in. Thanks
in advance.
