PLEASE HELP! This question is so confusing. Please help and explain! I will give thumbs up! THANKS!!!

Q6: Save and Load Functions (Using ifstream & ofstream) (20 points) // Q6a: saveDatabase() // Save the linked list of books to a file DB.txt using ofstream. I/You will need to come up with a way to store the number of members in linked list. That will help in load(). //One way to store is: // // // //KLibrary number of book1> // //knoOfBooks of book2> // // Hint: You may want to cast the enum 'Library' to an int before writing it to the file. // saveDatabase() is already called when exiting the program. You do not need to call it anywhere else. DB-Notepad File Edit Format View Help 3Computer Organization Algorithm Design intro to java This is one example of how to save the database in DB.txt. The '3' at the beginning is the number of books in the database. This number might be of help when implementing loadDatabase().
