Question

Problem 1: bookType

Design a bookType class that defines the book as an ADT. Some of the characteristics of a book are the title, author(s), publisher, ISBN, price, and year of publication. You only need to design the interface (.h file) and not the implementation (.cpp file)

• Each object of the class bookType can hold the following information about a book: title, up to four authors, publisher, ISBN, price, and number of copies in stock.
• To keep track of the number of authors, add another member variable.
• Include the member functions to perform the various operations on objects of type bookType. For example, the usual operations that can be performed on the title are to show the title, set the title, and check whether a title is the same as the actual title of the book.
• Similarly, the typical operations that can be performed on the number of copies in stock are to show the number of copies in stock, set the number of copies in stock, update the number of copies in stock, and return the number of copies in stock.
• Add similar operations for the publisher, ISBN, book price, and authors.
• Add the appropriate constructors.

bookType.h :

#include <iostream>
#include <vector>
#include<string>
#include <algorithm>
using namespace std;
class bookType
{
    private:
    
    string title;
    int nauthor;
    vector <string> author;
    string publisher;
    string ISBN;
    int copies;
    int price;
    string YearOfPub;

        vector <string>::iterator it =find(author.begin(),author.end(),s);

    bool isAuthor(string s)

    string getYearOfPub()

    void printAuthor()

        else
        {
            for(int i=0; i < author.size(); i++)
                cout << author.at(i) << "\n";
        }
    }
};

main(for testing) :

#include "bookType.h"
int main()
{
    vector <string> temp(0,"");
    bookType book1("Charles Darwin",temp,"Penguin Publishiong","ISBN1201231",10,100,"1984");
    cout<<book1.getPrice()<<"\n"<<book1.getYearOfPub()<<"\n"<<book1.getISBN()<<"\n"<<book1.getCopies()<<"\n"<<book1.getTitle()<<"\n";
    book1.addAuthor("Hello");
    book1.addAuthor("Mr Beast");
    book1.printAuthor();
    book1.removeAuthor("Hello");
    book1.printAuthor();
    cout<<book1.isAuthor("Mr Beast");
    vector <string> a = book1.getAuthor();
    cout<<a[0];
    book1.setPrice(10);
    book1.setTitle("Charles Darwin");
    book1.addAuthor("Mike Pence");
    book1.setYearOfPub("1984");
    return 10;
}

I've tested all the methods that I found complex, please let me know if it works!
