Program Plan Intro
List Member Deletion
Program Plan:
- Include the required specifications into the program.
- Declare a class ListNode.
- Declare the member variables “value” and “*p” in structure named “ListNode”.
- The data value of node is stored in variable v and address to next pointer is stored in pointer p
- Declare the constructor, destructor, and member functions in the class.
- Declare the structure variable “next” and a friend class Linked List
- Declare a class LinkList.
- Function to insert elements into the linked list “void add(double n)”is defined.
- Function to check whether a particular node with a data value n is a part of linked list or not “bool isMember(double n)”.
- A recursive print method is defined to print all the data values present in the link list “void rPrint()”.
- A destructor is called to delete the desired data value entered by the user called “LinkedList::~LinkedList( )”.
- A method to remove the element passed as a parameter from the link list is called “void LinkedList::remove(double x)”.
- Declaration of structure variable head to store the first node of the list “ListNode * head” is defined.
- A function “void LinkedList::add(double n)” is defined which adds or inserts new nodes into the link list.
- A function “bool LinkedList::isMember(double n)” is defined which searches for a given data value within the nodes present in the link list.
- A destructor “LinkedList::~LinkedList()” deallocates the memory for the link list.
- A function “void LinkedList::print()” is used to print all the node data values present in the link list by traversing through each nodes in the link list.
- A recursive member function check is defined called “bool LinkedList::rIsMember(ListNode *pList,double x)” .
- If the data value entered is present within the link list, it returns true, else it returns false.
- Declare the main class.
- Create an empty list to enter the data values into the list.
- Copy is done using copy constructor.
- Input “5” numbers from user and insert the data values into the link list calling “void LinkedList::add(double n)” function.
- Print the data values of the nodes present in the link list.
- Ask the user to enter an element to be removed.
- A loop is executed to traverse through the list and find the value entered.
- If the element is found, thelist1.remove (number) is called and the element is removed.
- The remaining list elements are printed.

Using a loop to reach the end of the list, write a code segment that deletes all the nodes in the list. Ensure the code performs all memory ‘cleanup’ functions.
Grocery shopping list (linked list: inserting at the end of a list)
Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node.
Ex. if the input is:
4
Kale
Lettuce
Carrots
Peanuts
where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list.
The output is:
Kale
Lettuce
Carrots
Peanuts
True or False The objects of a class can be stored in an array, but not in a List.

Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.arrow_forwardC++ Programming Language ::::::: Redo the same functions this time as nonmember functions please : NOTE: You can add only one function into the linked list class get_at_position which will return value of element at given position. 1) Insert before tail : Insert a value into a simply linked list, such that it's location will be before tail. 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_forward

- An iterable is an object that is similar to a list and is created by the range function True or Falsearrow_forward@6 The Reference-based Linked Lists: Select all of the following statements that are true. options: As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.arrow_forwardcard_t * moveCardBack (card t *head); The moveCardBack function will take the card in front of the pile and place it in the back. In coding terms, you are taking the head of the linked list and moving it to the end. The function has one parameter which is the head of the linked list. After moving the card to the back, the function returns the new head of the linked list.arrow_forward
