#include <string>
#include <iostream>

using namespace std;

class Book
{
private:
   string isbn, name, author, publisher;
   double price;
   int num_pages;
public:
   Book();
   Book(string p_isbn, string p_name, string p_author, string p_publisher, double p_price, int p_numpages);

   string get_isbn();
   string get_name();
   string get_author();
   string get_publisher();
   double get_price();
   int get_numpages();
   void set_isbn(string p_isbn);
   void set_name(string p_name);
   void set_author(string p_author);
   void set_publisher(string p_publisher);
   void set_price(double p_price);
   void set_numpages(int p_numpages);
   void display();
  

};

   Book::Book()
   {
       num_pages = 200;
       isbn = "default_isbn";
       name = "chegg.com";
       author = "user";
       publisher = "default_publisher";
       price = 100.00;
   }

   Book::Book(string p_isbn, string p_name, string p_author, string p_publisher, double p_price, int p_numpages)
   {
       num_pages = p_numpages;
       isbn = p_isbn;
       name = p_name;
       author = p_author;
       publisher = p_publisher;
       price = p_price;
   }

   string Book::get_isbn()
   {
       return isbn;
   }
   string Book::get_name()
   {
       return name;
   }
   string Book::get_author()
   {
       return author;
   }
   string Book::get_publisher()
   {
       return publisher;
   }

   double Book::get_price()
   {
       return price;
   }

   int Book::get_numpages()
   {
       return num_pages;
   }

   void Book::set_isbn(string p_isbn)
   {
       isbn = p_isbn;
   }
   void Book::set_name(string p_name)
   {
       name = p_name;
   }
   void Book::set_author(string p_author)
   {
       author = p_author;
   }
   void Book::set_publisher(string p_publisher)
   {
       publisher = p_publisher;
   }

   void Book::set_price(double p_price)
   {
       price = p_price;
   }

   void Book::set_numpages(int p_numpages)
   {
       num_pages = p_numpages;
   }

   void Book::display()
   {
       cout<<"isbn "<        cout<<"name "<< name <        cout<<"author "<< author <        cout<<"publisher "<< publisher <        cout<<"price "<< price <        cout<<"number of pages "<< num_pages <    }

In book.cpp

#include "book.h"

int main()
{
Book obj1("default_isbn", "compilers", "I dont know", "random publisher", 100, 200);

obj1.display();

}

Explanation / Answer

I assume that Content of Books.txt is:

IND123
Computer Network
Robert Krush
GMT HIll
432
340

Then Please find book.cpp

#include "book.h"
#include<fstream>
#include<iostream>

using namespace std;

int main(){

   ifstream readBook("Books.txt");
   string isbn;
   string name;
   string author;
   string publisher;
   double price;
   int pages;

   while(!readBook.eof()){
       getline(readBook, isbn);
       if(isbn.empty())
           break;
       getline(readBook,name );
       getline(readBook, author);
       getline(readBook, publisher);
       readBook>>pages;
       readBook>>price;
    
       // creating book object with all user data
    
       Book obj1(isbn, name, author, publisher, price, pages);
       obj1.display();
        
   }

   return 0;
}
