I was wondering if there was any good reading regarding using null values in C++. Currently, in the program I'm working on for learning C++, when someone adds a person to edit values on, I have all of the values set to 0. I'd much rather have the values set to a null value. AKA they would be "initialized" but not really. I could rewrite some of the code to check for NULL values and respond appropriately in display, etc...
