Write a program $($in C$++$ only$)$that implements a simple e$-$library management system. The program should provide a menu which allows the user to do the following:

Add A New Book

Edit Details of an Available Book

Delete A Book

Display All Books in the Library

The book class contains the following attributes:

Publication ID $($This is unique, you must use this variable for searching purposes$)$

Book Title

Author$($s$)$

List of Patron Subscribers

The program should prevent the addition of duplicate book entries using the unique publication ID$.$ The program should be implemented using character arrays only $($using string is prohibited$).$ Additionally, you should consider using OOP concepts such as classes or structs, default or parameterized, and copy constructors in your program.
