Modify the menue so that it contains five options. //ADD Record, Display Record, Display Total Sales, Display Average sales, //and Exit. When the user selects the Display Records option, the program should call //a function to display the contents of the sales.txt file on the screen. When the user // selest the Display Average Sales option, the program should call a function to calculate // and display the average sales amount stored in the file. Test the options and uplaad to the // assignment link.saves records to a sequential access
