Custom types

This works well for all the primitive types, but what about when you make your own typedef struct or class?

In cases like this, I just wing it and do whatever seems logical at the moment:

For instance, if we have a class ListIterator, an instance of that class could be ListIterator *pliIterator (local pointer to a ListIterator object named Iterator).

Note: I built this page off the top of my head based on what I use all the time. Other people go by different hungarian notation rules.
If something is blatantly wrong, send me an email and I'll fix it.
