   Inside the isEqual member function of B, a call to isEqual will result in
a recursive call back to the same member funcion. To call A's version of
isEqual, you need to use scope resolution. You can do this as follows:
 
B::isEqual()
{
    return (... && A:isEqual() );
}

Simple huh! In fact the call to B's isEqual() member function can be structured
the same way (ie: B::isEqual() ), but it is implicit that you are calling B's
member functions from within a member of B.
