Program Plan Intro
List Reverse
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)”.
- Declare a method “void reverse( )” to reverse the elements present in the link list by traversing through the list and Move node at end to the beginning of the new reverse list being constructed.
- 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.
- Call the reverse function “list1.reverse()” to reverse all the elements in the link list and then call the print function to print the reversed elements.

C++ function Linked list
Write a function, to be included in an unsorted linked list class, called replaceItem, that will receive two parameters, one called olditem, the other called new item. The function will replace all occurrences of old item with new item (if old item exists !!) and it will return the number of replacements done.
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
Reference-based Linked Lists: Select all of the following statements that are true.
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.
