Description: You are going to write a ++ program to perform this function. You will define a structure called book list that will hold a number associated with each book (int), book title (string), author (string), a description of the book (string), a date when the book was read stored in 2 parts- month (int) and year (int] and a rating of the book (int).The number will be generated by the program as each book is entered. The rating should be limited to a number between 1 and 10. It will bea scale the user can enter what they thought of the book. Your program is to check to see if a file called "reading_list.txt already exists and if it does, read it into an array of structures of type book list. The program will execute until the user selects 6 to exit the program. The program should have a menu that asks the user to 1) print books 2) enter a new book 3) modify a book 4) print how many books are in the list 5) print all the books that have a certain rating 6) exit the program. If the user enters 1, all the books will be printed to the screen including the book number. If the user enters 2, the program will ask the user for the title, author description, date, and rating. If the user selects 3, the program should ask the user for the book number to be modified and all the new information for that book. If the user selects 4, you are to print the total number of books in the database to the screen. When the user enters 5, you are to ask for the rating and then print out only the books with that rating. When the user selects 6 to exit the "reading_list.oxt". Structure member definitions:. Book number-to be generated by the programmer for each new book that is entered Book title-This should be able to hold spaces Author-should be able to hold spaces Description-should be able to hold spaces. Date should be a month stored as 1-12 and year stored with all four digits, i.e. 2017. It should be printed as Xx/xxxx i.e. 9/2016 when printing it to the screen. Rating- should be a number between 1 and 10 Requirements: . Create an array of structures containing the structre members as defined above The program needs to be able to handle data for up to 500 books. Read the data from the file "reading-list.txt" and save each book record in a structure in your array when you start your program. (Only read once.). Write to the file once when the user selects exit. The title, author, and description should be able to contain spaces. Book numbers must start with 1 and be generated by the program You need to keep track of how many books there are. You must use a switch statement for the menu selection. DO NOT use break statements except in the switch statement. program, you are to create a new file or overwrite the existing file and write each record to the text file Sample output: if 1 selected 1 Les Miserables Victor Hugo About a released prisoner and his changed life 9/2016 10 2 of Men and Angels Bodie Thoene About the Irish discontent 7/2015 8 Sample input: if 2 selected Enter title: Raising Boys Enter author: James Dobson Enter description: A book on raising boys Enter month: 01 Enter year: 2017 Enter rating: 9 Sample input if 3 selected Enter part to modify: 11 Les Misrables Victor Hugo About a released prisoner and his changed life 9/2016 10 Enter title: Les Misrables Enter author: Victor Hugo Enter description: About a changed life Enter month: 12 Enter year: 2016 Enter rating: 10 Sample output if 4 selected Total number of books: 3 Sample output: if 5 selected Enter rating: 10 1 Les Miserables Victor Hugo About a released prisoner and his changed life 9/2016 10 Reminder:. Hints: The first item in the file should be the number of books. Writing this information out will make file processing much easier. The easiest way to read and write the information for this assignment is to put each item on a new line. Cin alone does not read in a line with spaces
