Make a program that allows the user to enter data for as many InventoryItems as he or she wants. All InventoryItem product numbers should be between 1 and 49. If the user attempts to enter a product number greater than 49, force the user to reenter the number. Store each record at a disk location for which the value equals the product number times the size of an InventoryItem object. Save the file as InventorySystemDataEntry.cpp.
