Expert Solution & Answer
Chapter 17, Problem 5SA
Explanation of Solution
If the fourth node of a linked list is to be deleted, and p points to the fourth node then a pointer to the third node is also needed. This is so because after the deletion the link member of the third node needs to point to the next node after the node being deleted in order to keep the list in a linked condition...

Given that head points to the beginning of a singly linked list, tail points to the last
node of the linked list, current points to the current node and tmp points to any node
in the linked list. Assume that each node of the linked list contain two data which are
studentID of type int and studentName of type string and a link to the next node
called next.
(a) Draw a diagram to show the linked list of the above situation. Assume that
currently, the linked list contains 5 nodes.
(b) Write C++ statement to do the following:
i. Declare a structure to define a node for the above mentioned linked list
together with the mentioned pointers.
Question 14
Consider a Double Linked List with just one node and then select the correct statement:
The head and the tail point to the same node in the list
b. The head points to the node but the tail points to null
Both the head and the tail points to each other
C.
d.
The tail points to the node but the head points to null
