I am needing to write a program for a book monitoring. I need help with creating $3$ classes. I know I want them to be be book, library, and author$/$narrator classes. I just need help understanding how to do so$.$ It should follow these details:: Please upload all three $.$h files for your class $($more if you are doing more than $3$ classes$).$

All members and method declarations should be there $($you can change them later if needed$).$

You will need to put a comments with the methods that will be your substantial ones in the class that includes a description of what you plan on doing with that method.

Reminder:: Substantial means there is at least one if$/$switch$/$loop$,$ etc.
