Answer: head

Step by step solution

01

Understanding Linked Lists

A linked list is a dynamic data structure in which each element (called a node) contains a data part and a reference (or link) to the next node in the sequence. Linked lists use pointers to keep track of the next element in the list. Traversal is done by following these pointers one after the other until the end of the list is reached.
02

First Node in a Linked List

The first node in a linked list is important because it serves as the entry point for accessing the rest of the list. It is the starting point from which we can traverse the list and access its elements. The term we are looking for that points to the first node is called the __head__.

Recap

In a linked list, the _______ points to the first node in a linked list. The term that fills the blank is called the __head__. The head is important as it serves as the starting point for traversing the list or accessing its elements.

What type of linked list is the STL list container?

Find as many mistakes as you can. void NumberList::appendNode(double num) { ListNode *newNode, *nodePtr; // Allocate a new node & store num newNode = new listNode; newNode->value = num; // If there are no nodes in the list // make newNode the first node. if (!head) head = newNode; else // Otherwise, insert newNode. { // Find the last node in the list. while (nodePtr->next) nodePtr = nodePtr->next; // Insert newNode as the last node. nodePtr->next = newNode; } }

\(\mathrm{T} \quad \mathrm{F} \quad\) Linked lists are not superior to STL vectors.

Consider the following code: struct ListNode { int value; struct ListNode *next; }; ListNode *head; // List head pointer Assume that a linked list has been created and head points to the first node. Write code that traverses the list displaying the contents of each node’s value member.

After creating a linked list’s head pointer, you should make sure it points to __________ before using it in any operations.
