Could you please solve the question with C++ and <class> ? thank you
Write a program that simulates a Library Circulation System. The system allows: 1. Adding and saving a new book record. 2. Searching for a book by title. 3. Searching for a book by author. 4. Searching for a book by ISBN number 5. Check out a book 6. Check in a book 7. List books by status. 8. Display library collection sorted by title. 9. Display library collection sorted by author. A library book can be defined as a structure struct book { string author; string title; string isbn; int copies; }; Book status can be defined as an enum enum status (CHECKED_OUT, ON_SHELF); submission 1. source code 2.test casesExplanation / Answer
