Develop a menu driven C++ program to manage the College of Science Book Store. Your program should maintain three lists: one for books, another one for students and a third one for the loans transactions. When your program starts it should read the books information, students information and loans information from three separate files "books.txt", "students.txt" and "loans.txt". An example format of these files is shown below. You need to: 1. Design and implement a Book class to encapsulate a book object. Each book has title, author, ID and number of copies. Assume book IDs are unique. 2. Design and implement a Student class to encapsulate a student object. Each student has name and ID. Assume student IDs are unique. 3. Design and implement a Loan class to encapsulate book loan transactions in the book store. A Loan object has the Book ID, the Student ID, and the semester when the book is borrowed (e.g. SP10)
