You probably don't want to use a reference instead of a pointer since there
is much more opportunity to leak memory.  If you were to use a reference you
would have to cast the new memory as well, and then remember to derefernce
the memory as well:

NumData & myNumData = *(new NumData(1, 10); myNumData.displayInfo());
. . .
delete &a;
