CS 16 Plan for Today, 3/5/2018:

Review PA5 solution

Remind pointer ideas, dynamic variables [09-02.cpp]

typedef - can be used to simplify type names
	typedef double *DoublePointer;
	DoublePointer dp; // same as (double *dp)

Array names and pointers to array values
	[09-04.cpp and Display 9.5]	
	
Dynamic array [09-06.cpp]
	Need [] to delete: delete [] array;

Pointer arithmetic rules (within arrays only):
	Add or subtract integer okay
	Okay subtract pointer from pointer [ch demo]
	No multipication or division

Pointers to pointers - not in text per se [ch demo]
	But used for 2-D dynamic array [09-07.cpp]
	btw, command line args again [args2.cpp]
