It's spelled "0". I don't see what difference a null keyword would > make. void f( int ) ; void f( void* ) ; void g() { f( 0 ) ; // calls f( int ) f( null ) ; // should call f( void* ) } The question isn't whether C++ needs a null keyword, it is rather whether it is possible to add one without either watering down to the point of making it useless, or breaking too much existing code. (I happen to think it possible, but it is a question on which reasonable people can differ. At to whether C++ would be better off with a real, working null keyword, on the other hand, there really isn't much discussion possible.) -- James Kanze mailto: James.Kanze@dresdner-bank.com Conseils en informatique orientie objet/ Beratung in objekt orientierter Datenverarbeitung Ziegelh|ttenweg 17a, 60598 Frankfurt, Germany Tel. +49 (069) 63 19 86 27 -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own --- [ comp.std.c++ is moderated.
