// The program will read an inventory file into 3 parallel arrays.
// One array will contain strings for Item Description
// One array will contain doubles for Cost Per Item
// One array will contain doubles for No. of Items and item Shippable status.
// The program will present a menu presents a user with 4 choices:
// 1. Read the inventory file, 2. Display the Inventory,
// 3. Write the inventory to a file, 4. Exit the program.
// The program should validate user input for a valid menu option.
