The source code for this program (retail.cpp) and its
executable (retail.exe) must be available in your home directory (i.e.,
cpsuser3.cps.udayton.edu/cps150/sectionn1/cps150-N1.[your number goes here])
by 5:50p on Thursday, September 16, 2004. Also, turn in
a printout of your code in class, before class starts.
Note: You must use the filenames exactly as shown above (i.e., all lower case).
Algorithm: A complete and type-written algorithm is due

A mail order house sells five different products whose retail prices are shown in the
|Product number ||Retail price|
Write an efficient (no unnecessary operations/comparisons)
program that reads a series of pairs of numbers as follows:
Your program should use a switch() statement to help determine the retail
price for each product. Your program should calculate and display the total retail value
of all products sold.
- Product number
- Quantity sold for one day
An input file contains a single integer indicating how many pairs of
integers (i.e., the first integer in the file indicates how many pairs must be
processed). Each pair of integers is a product number followed by the quantity
sold for that item. The input file will be error-free. Be sure to test your
program with several different input streams. There is a sample input file
Output: Print an aligned, well-spaced table with labeled columns.
The rows and columns must appear exactly
as below, and the last column should be totaled.
product retail total proceeds
number price number by product
$ sold $
Use a switch() to accumulate both the total number sold
for each product.
Set the field width and precision to print aligned output.
Declare each retail price as a symbolic constant:
const double RET_PR_1 = 2.98
const double RET_PR_2 = 4.50
const double RET_PR_3 = 9.98
const double RET_PR_4 = 4.49
const double RET_PR_5 = 6.87
