Point of interest:  delete [] vs. normal delete

Base vs. Abstract data types	
	Base data type (or primitive data type)
	Abstract data type
		Encapsulates data and operations
		How does the example from last class hold up?

C++ classes:
	One that does something (like, heading for a 3D game)

ADT operations (typical):
	insert
	delete (do we care about order?)
	access
	modify
	search
	traverse

Could our example be an ADT?
	Sure
	Let's add the above operations

traverse:  This one is a little tricky to encapsulate
	Just let the user use whatever access we have?
	Take a function pointer, and use map?
	Iterator class, like MFC?
	Should it be mutable?
	If we get this one, we could make numbers a private data member

Since we've gone this far (if we get here)
	Could it expand as needed?
	How about contract as needed?
