Chapter 17, Problem 1RQE
Program Description Answer
The “head pointer” points to the first node in a linked list.
Expert Solution & Answer
Explanation of Solution
Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.
Head pointer:
The purpose of head pointer is to point the node of head node or first node in the linked list and it is also called as “list head”; if the head pointer points to a null value, then it is considered that the list is empty.
Graphical representation of head pointer:
The graphical representation of head pointer is as follows:

ASSUMING C LANGUAGE
True or False: You can have the data portion of a Linked List be a Struct containing a Linked List itself
A linked list can hold ______ nodes
10
100
1000
a number specified when the linked list is instantiated.
any number of
struct node{
int a;
struct node * nextptr;
};
Write two functions. One for inserting new values to a link list that uses the given node structure.
void insert(struct node **head, int value);
Second function is called to count the number of even numbers in the link list. It returns an integer that represents the number of even numbers.
int countEvenNumbers(struct node *head);
Write a C program that reads a number of integers from the user and insert those integers into a link list (use insert function). Later pass the head pointer of this link list to a function called countEvenNumbers. This function counts and returns the number of even numbers in the list. The returned value will be printed on the screen.
Note 1: Do not modify the function prototypes.

- 1 Singly Linked List A linked list is a data structure where elements are connected to form a chain where each node points to the next one in the order. Exercise: Given the code of the Node struct, implement a singly linked list with the following functionalities: • addFront: add an integer key to the front of the list. • remove: deletes the smallest number larger than or equal the passed integer and returns the deleted value. If no number is found, returns -1. All cases must be handled. You can define any helper method as needed. #include #include #define INF INT_MAX // indicates infinity value using namespace std; struct Node int key; Node next; Node(int key) { this->key - key; this->next- NULL; }; class SinglyLinkedList public: SinglyLinkedList () head - NULL; void addFront (Node* node) 1 int remove(int val) { private: Node head; }; int main() { SinglyLinkedList sLL - neu SinglyLinkedList (); Node* nodel = new Node (5); Node node2 - neu Node (13); Node node3 - nev Node(7);…arrow_forwardCircular linked list is a form of the linked list data structure where all nodes are connected as in a circle, which means there is no NULL at the end.

The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order: 1. Create a new Node object. 2. Make the data variable in the new Node object reference the object that was passed to addFirst. 3. Make the next variable in the new Node object reference the object that is currently referenced in variable first. 4. Make variable first reference the new Node.

So if a list contains {1, 2, 3}, insert before tail value 9 is called, the list will become {1, 2, 9, 3}. 2) Insert before value : Insert a value into a simply linked list, such that it's location will be before a particular value. So if a list contains {1, 2, 3}, insert before 2 value 9 is called, the list will become {1, 9, 2, 3}. 3)Count common elements : Count common values between two simply linked lists.So if a list1 contains {1, 2, 3, 4, 5}, and list2 contains {1, 3, 4, 6}, number of common elements is 3. 4) Check if sorted : Check if elements of simply linked lists are sorted in ascending order or not.So if a list contains {1, 3, 7, 8, 9}…arrow_forwardstruct remove_from_front_of_dll { // Function takes no parameters, removes the book at the front of a doubly // linked list, and returns nothing. void operator()(const Book& unused) { //// TO-DO (13) |||| // Write the lines of code to remove the book at the front of "my_dll", // // Remember, attempting to remove an element from an empty data structure is // a logic error.
