Bookshop management system using file handling in C++

We see different software in every hospitals or library to manage their database. It is very important to store organization’s data. So we use this software. Now we are going to develop a similar type of system by using C++.  Here, we will make a bookshop management system.

The information of a particular book:

1. Book name
2. Author Name
3. Number of books
4. Book ID

We will use switch case to go to different functions. The main functions of the system will be:

1. Add book
2. Show book
3. Delete book
4. Check book
5. Update book

So following is the implementation of the functions using switch case and file handling in C++:

Code-

//Bookshop management system using C++ file handling
#include <fstream>
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
class books {
public:
	void options();
	void bookadd();
	void bookshow();
	void bookcheck();
	void bookupdate();
	void bookdelete();
};
void books::options()
{
	system("cls");
	cout << "\n\n\t\t\t\tCONTROL PANEL";
	cout << "\n\n1. ADD BOOK";
	cout << "\n2. DISPLAY BOOKS";
	cout << "\n3. CHECK PARTICULAR BOOK";
	cout << "\n4. UPDATE BOOK";
	cout << "\n5. DELETE BOOK";
	cout << "\n6. EXIT";
}


// addition of book
