C++

We now have a list of books (in the form of an array of Book objects) and a list of users and their ratings (in the form of an array of User objects).

We now update the getRating function from last week to use these arrays of User and Book objects , to search for a particular users rating for a particular book title. Write a function that, given a users name and a books title, returns the rating that the user gave for that book.

• Your function MUST be named getRating.

• Your function should take 6 input arguments in the following order:

  • string: username

  • string: title of the book

  • Array of User objects: users

  • Array of Book objects: books

  • int: number of users currently stored in the users array

  • int: number of books currently stored the books array

• The username and book title search should be case insensitive. Ben, ben and BEN are one and the same user.

• If both the user name and the book title are found in the arrays, then the function should return the users rating value for that book title.

• The function should return the following values depending on cases:

  • Return the rating value if both user and title are found

  • Return -3 if the user or the title are not found

here is the .h file

#ifndef BOOK_H #define BOOK_H #include  using namespace std; class Book { private: string title; string author; public: Book(); Book(string title, string author); string getTitle() const; void setTitle(string title); string getAuthor() const; void setAuthor(string author); };

#include "Book.h" Book::Book() {} Book::Book(string title, string author) : title(title), author(author) {} string Book::getTitle() const { return title; } void Book::setTitle(string title) { this->title = title; } string Book::getAuthor() const { return author; } void Book::setAuthor(string author) { this->author = author; }
