Program Plan Intro

List Print

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)”.
    • 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.
  • 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.

Blurred answer
Students have asked these similar questions
struct Node { int data; Node * next; }; Node • head; a. Write a function named addNode that takes in a variable of type int and inserts it at the head of the list. b. Write a function named removeNode that removes a node at the head of the list.
Remove Duplicates This function will receive a list of elements with duplicate elements, this function should remove the duplicate elements in the list and return a list without duplicate elements. The elements in the returned list must be in the same order that they were found in the list the function received. A duplicate element is an element found more than one time in the specified list.
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.
