//  Orders
/*
This is a program that calculates information about orders
of shirts and pants. All orders have a quantity and a color.
The program will then go through the array to calculate and print,
properly labeled:
•The total number of shirts ordered and the total price
•The total number of pants ordered and their total price
•The average waist size (to one decimal place)
•The average inseam length (to one decimal place)
