// Write your name here

// Write the compiler used: Visual studio or g++

// READ BEFORE YOU START:

// You are given a partially completed program which consist of a class 'Book' defined in book.h

// The definitions of class member functions are to be filled in book.cpp

// hw09q1.c (this file) creates an array of objects 'b[]' and uses a menu driven program to add a book, display book info,

// sort the book list and to find the newest book(by publication year).

// You should start completing the program beginning from Q1. Question numbers are given around line 31.

// To begin, you should trace through the given code and understand how it works.

// Please read the instructions above each required function and follow the directions carefully.

// If you modify any of the given code, the return types, or the parameters, you risk getting compile error.

// You are not allowed to modify main ().

// ***** WRITE COMMENTS FOR IMPORANT STEPS OF YOUR CODE. *****
