C++ program
Write a C++ program You have to implement a searchable textbook database. This will allow the user to search for the author (or ISBN or publisher, etc.) for a book with a particular title, as well as finding all books by a particular author, among other things. You will implement 2 classes: Book and BookDatabase The Book class must contain: A string for the title and publisher, an integer for the year of publication, and a vector (or list, or set) of strings for the author. (You can choose whichever one you want (You may write as many private functions as you would like to help your implementation.) Book(const string&title;, const string&publisher;, int yearOfPublication, string" authors, int numAuthors); This is the book constructor t l initialize all the member variables and al so store all of the authors names in the container that will hold these names bool operator (Book&bl;, Book& b2); This will return true iff the two Books have the same title. (You can assume that the database will not contain 2 books with exactly the same title bool operator(Book&bl;, Book& b2); WThis will return true iff the title of bookl is lexicographically before the title of book2. This will print a representation for a Book ostream& operatorExplanation / Answer
