Write a menu-driven multiform inventory program for a bookstore with data saved in a text file. Each record of the text file should consist of 5 fields-title, author, category (fiction or nonfiction), wholesale price, and number in stock. At any time, the program should display the titles of the books in stock in a listbox. The user should have the option of displaying either all titles or just those in one of the two categories. The user should be able to add a new book, delete a book, or alter any of the fields of a book in stock. The adding and editing processes use the second form, frmDetails. At any time, the user should be able to calculate the total value of all books, or the total value of the books in either category. The menu item File contains the two second-level menu items Save and Exit. The menu items Display and Values each contain the three second-level menu items All, Fiction, and Nonfiction. (Note: Store the data about the books in an array of structures.)
