1. Parallel Arrays
Two arrays are said to be parallel if subscripted variables having the same subscript are related.

2. A retail store has five bins, numbered 1 to 5, each containing a different commodity. At the beginning of a particular day, each bin contains 45 items. Table 1 shows the cost per item for each of the bins and the quantity sold during that day.
Write a program to:
Place the cost per item and quantity sold in parallel arrays
Display a table giving the inventory at the end of the day and the amount of revenue from each bin
Compare the total revenue from each bin
List the number of each bin that contains fewer than 20 items at the end of the day
Bin
Cost Per Item
Quantity Sold 1 3 10 2
12.25 30
37.45 9 4
7.49 42 5
24.95 17
