In C++, 0 is an abused integer. It is used to reflect, well, 0 as a value of type int and it is also used to represent a null pointer... The latter has led to many bugs and confusion over the past 30 years. Put simply, using 0 is and has always been a bad idea (then there's the NULL macro...). Well, my friends, today, with the release of Visual Studio 2010 Beta 2 and the updated C++ language, compilers and libraries that come with it, the abuse of 0 comes to an end: Introducing nullptr the rvalue constant that actually is a null pointer literal.
Who better to dig deep into nullptr (and a few other topics of related interest and importance) than the great and gifted Stephan T. Lavavej? Stephen is a C++ expert and library author who you've met before a few times on C9. Sit back, relax and learn everything you ever wanted to know about nullptr. Thank you, Stephen, for the awesome lesson!
Enjoy!
