The Spread-a-Smile Greeting Card Store maintains customer records with data fields for first name, last name, address, and
total purchases in dollars. At the end of each month, the store manager invites the five customers with the greatest value of purchases to an exclusive sales event. Develop the logic for a program that reads in 100 customer records and stores the first and last names and total purchases in three parallel arrays. Then sort the arrays so that records are in descending order by purchase amount for the month. The output lists the names of the top five customers.
