The number in parentheses at the end of an exercise refers to the learning objective listed at the beginning of the chapter.

Suppose that the fourth node of a linked list is to be deleted, and p points to the fourth node? Why do you need a pointer to the third node of the linked list? (3)

Consider the linked list shown in Figure 17-50. Assume that the nodes are in the usual info-link form. Use this list to answer Exercises 6 through 14. If necessary, declare additional variables. (Assume that list, current, temp, trail, and last are pointers of type nodeType.)
