Because pFirstname is NULL now zap(pLastname); zap(pJobDescription); int *iiarray = new int[10]; zaparr(iiarray); There is nothing magical about this, it just saves repetetive code, saves typing time and makes programs more readable.

Hey OLIVES jean-Michel, I love hearing when another developer bashes Microsoft “Bloatware” and realizes that Delphi is still the best language on the market for Win32 Applications!
