    The & Operator Reference To There are several ways to compute a reference to a pointee suitable for storing in a pointer. The simplest way is the & operator. The & operator can go to the left of any variable, and it computes a reference to that variable. The code below uses a pointer and an & to produce the earlier num/numPtr example.

   It is possible to use & in a way which compiles fine but which creates problems at run time the full discussion of how to correctly use & is in Section 2. For now we will just use & in a simple way.

   The * Operator Dereference The star operator (*) dereferences a pointer. The * is a unary operator which goes to the left of the pointer it dereferences. The pointer must have a pointee, or it's a runtime error.

   Example Pointer Code With the syntax defined, we can now write some pointer code that demonstrates all the pointer rules...


void PointerTest() {
// allocate three integers and two pointers
int a = 1;
int b = 2;
int c = 3;
int* p;
int* q;
// Here is the state of memory at this point.
// T1 -- Notice that the pointers start out bad...
