Question
I need help to write this C++ program.
Description: This program is going to define a preparatory class that you will be using for linked list. You are going to write this class and use it so that you will be ready to use it for the linked list class. The class is going to be the Node class.
Node class data:
* Book title – must hold the title of a book including spaces.
* Author – must hold the author’s name including spaces
* Date read – must be able to contain numerical mo, day, year (4 digits)
* Pointer to class Node Node class member functions
* Default constructor
* Constructor that takes book title, author, and date
* Mutator function to set pointer
* Accessor function to return pointer
* Accessor function to return book title
* Accessor function to return author
* compare_data function that will compare a given book title against the one in the class
* process_data function that will print the data to the screen.
Explanation / Answer
Here first we will see how to create a class for linked list.
First we will use Private and Public Access Modifiers to define the class.
class LinkedList
{
private:
Node *_pHead;
Node *_pTail;
public:
LinkedList(void);
LinkedList(int val);
LinkedList(void);
}
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
Please find the below Linked list class of C++ for mentioned Node class data
#include <iostream.h>
#include <conio.h>
#include <iomanip.h>
struct book

char booktitle [20], author [20], dateread [20];
