For tests $7$ and $8$ you will end up writing your own class, called Book, make an instance of it$,$ and return the result of that method. The Book class should be included in a new Book.cpp file.

To create your TextCodec class, add the following access modifier, fields, constructor and methods.

In addition, add the line #define BOOK at the top of Book.cpp

For example:

#define BOOK

class Book

$\{$

$//$ fields of this class

$//$ constructors of this class

$//$ methods of this class

$\}$

Your Book class must have two member variable $($field$),$ which is:

a string, which holds a title

a string, which holds an author

You can name the field any name you want.

Your book will have a default constructor and an overloaded control. By default, the default constructor should:

Set the title to "Moby$-$Dick"

Set the author to "Herman Melville"

In addition, your book should have an overloaded constructor that accepts both an author and a title and sets the appropriate fields.

Finally, your book will need accessors for both the Title and Author. Remember, these must both be under the public heading to be accessible.

For example:

public:

string GetAuthor$()\{$

$//...$

$\}$

string GetTitle$()\{$

$//...$

$\}$

For these Test, when you have finished adding the above$-$requested information to your Book class, you will then make an instance object of type Book, calling the appropriate constructors.

For example:

Book book$1$;

return book$1$;

Book book$2($title$,$ author$)$;

return book$2$;
