Write a C++ program that specifies three one-dimensional arrays named price, quantity and total. Each array should be capable of holding 8 elements. Use a loop in the input function to read the values for the price and quantity arrays. The entries in the total array should be the product of the corresponding values in the price and quantity arrays (i.e. total[ i ] = price[ i ] * amount[ i ]). After all the data have been entered, display the following output:

	Price	Quantity	Total
	-----	--------	-----

a.) Use main( ) as your driver function. Write main( ) so that it allows the user to run the program as many times as desired, as indicated by input from the user.

b.) Write appropriate functions that main( ) calls to accomplish the following tasks:

Get the prices and quantities from the user (perform data validation on the users input),

Calculate the totals

Display the required output as shown below.

Sample Input:

This program computes the total price of different sale items based on the purchase price and the quantity of each item sold.

Please enter the price and quantity of 8 items.

Price of item 1 = ? 2.5

Quantity of item 1 = ? 3

Price of item 2 = ? 5.5

Quantity of item 2 = ? 4

Price of item 3 = ? 7.3

Quantity of item 3 = ? 6

Price of item 4 = ? 5

Quantity of item 4 = ? 6

Price of item 5 = ? 9

Quantity of item 5 = ? 4

Price of item 6 = ? 5

Quantity of item 6 = ? 8

Price of item 7 = ? 4

Quantity of item 7 = ? 32

Price of item 8 = ? 54

Quantity of item 8 = ? 4

Sample Output:

The sales summary is:

Price($) Quantity Total($)

--------- ---------- ---------

2.50 3 7.50

5.50 4 22.00

7.30 6 43.80

5.00 6 30.00

9.00 4 36.00

5.00 8 40.00

4.00 32 128.00

54.00 4 216.00
