Not true.  Check out RTTI (part of the C++ standard).

In any case, this approach is very non-OO.  What you really want are 
multimethods, i.e. functions for which the dispatch depends on more than 
one virtual parameter (which neither C++ nor Java has direct support for).  
As an example, check out:

Note the classic multimethods example is overlap() which might give you 
a hint that it's useful for this problem.
