It lets users store and manage printed books and audiobooks, with searching, sorting, statistics, and saving and loading data from a file. I demonstrate adding four printed books and four audiobooks, searching by title, author, genre, and type, sorting by title and cost, and showing statistics like total cost, average pages or duration, and books per genre. I also show edge cases with zero and large values, then save to books.txt, exit, and reload to verify data integrity. No action is requested from viewers."}
