Operations with pointers

At this point, the only operations that work reasonably with pointers are the following:

• Assignment
• Accessing pointer targets
• Limited pointer arithmetic
• The comparison of pointers

We will explore each of these in turn. As we do, we must also consider the NULLspecial pointer value (the zeroth address), or null pointer, and the void *special, unspecified pointer type, orvoid pointer type.
