I need to change the updated menu like this: ( For updating the book, the code requests the ID for the book that needs updating. It would be good if you could provide a way for the user to get the ID. At the moment the implementation is an auto-generated ID and there is no way for the user to know what this is. When the user also wants to update a book, the user might not want to update all the fields. Maybe the user just wants to fix a typing error for the author or title. Please provide a way for the user to skip fields they do not want to update. An option here might be to leave the field blank and then don't update the fields with blank inputs. Note that if you want to follow this example then you will have to communicate this to the user.) and; For deleting the book, the code also requests the ID for the book.
