Consider the linked list shown in Figure 16-50. 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.)

Mark each of the following statements as valid or invalid. If a statement is invalid, explain why.

a. current = list;

b. temp->link->link = NULL;

c. trail->link = 0;

d. *temp = last;

e. list = 75;

f. temp->link->info = 75;

g. current->info = trail->link;

h. *list = *last;

i. current - last;

j. cout << trail->link->link->info;
