Write a program that a small business owner can use to track customers. Assign each customer a number (starting at 0). Whenever a customer purchases something, record the sale in the element that matches the customer’s number (the next unused array element). When the store owner signals the end of the day, print a report consisting of each customer number with its matching sales, a total sales figure, and an average sales figure per customer (use a while loop). Print code and sample run.
