Write a Program Library Management System

Object: Write a menu driven program that depicts the working of a library. The menu options should be:
a) Add book information b) Display book information c) List all books of given author d) List the title of specified book e) List the count of books in the library f) List the books in the order of accession number g) Exit. 
Create a structure called library to hold accession number, title of the book, author name, price of the book, and flag indicating whether book is issued or not.

Code:

#include<iostream>
#include<conio.h>
#include<string>
using namespace std;
void addbok();
void dipbok();
void bokaut();
void count();
void listacc();
void assacc();
