Expert Solution & Answer
Chapter 19, Problem 3FTE
Explanation of Solution
Purpose of the given code:
The given code is used to add a node to the beginning of a doubly linked list “myList”.
Given code:
//Add an element "Abraham" to beginning of list "myList"
myList = new Node("Abraham", myList, null);
Error in the given code:
User need to set the “prev” reference of the second node. So, user needs to add below line to the given code:
/* If next node of "myList" is not equal to "null", then */
if (myList.next != null)
/* Set the reference of second node to "myList" */
myList.next...

Students have asked these similar questions
int F(node<int>&p){int c=0; while(p!=0){p=p->next; c++; } return c;} This function is a. return the number of items in the linked list b. return the number of items in a linked list and destroy the linked list c. None of these d. destroy the list and free all allocated nodes
The following method is defined within a linked list class. What does it do?
void MyList::doSomething() { Node* p = head;
while (p) { cout << p->value << " "; p = p->next; }}
Group of answer choices
inserts a node into linked list
deletes a node from linked list
displays contents of linked list
destroys the entire linked list
True or FalseA Circular Linked List has a special method called revolve() that shall move the tail reference to the previous node.
