These are fairly straight forward and are easily defined. Consider the following:
the operator lets us access a member of the structure pointed to by a pointer.i.e.:
pt_ptrx = 1.0;
pt_ptry = pt_ptry - 3.0;
Example: Linked Lists
Fig. Linking Two Nodes
NOTE: We can only declare next as a pointer to ELEMENT. We cannot have a element of the variable type as this would set up a recursive definition which is NOT ALLOWED. We are allowed to set a pointer reference since 4 bytes are set aside for any pointer.
The above code links a node n1 to n2 (Fig. ) we will look at this matter further in the next Chapter.
