Sheets R Us, a company that specializes in linen sales at the lower end of the market, is opening a new automated store to sell sheets and pillow cases.  Your job is to write a program to deal with the customers who enter their orders through one of the store's order stations (containing a monitor, a keyboard and a display of patterns).  Sheets R Us sells individual sheets, fitted or flat, pillow cases, and bedding sets(two sheets and two pillow cases)  for all standard sized beds.  The base cost for a standard King set using material that contains 300 threads per square inch is $70.  For a similar Queen set, it is $60; for a Full set, it is $50; and for a Twin set, it is $40.

Your program needs to greet the customer and then ask a series of questions (prompts) to determine the cost of the items being ordered.  Specifically, the program needs to do the following:

1. Determine what size sheet is being ordered.  The possible sizes are King, Queen, Full, and Twin.  The program must accept one of these four words as the size.  If the customer enters anything else, the program should tell the customer that the entry is invalid and give the customer a second chance.  If the second customer try is also invalid, the program should terminate after telling the customer s/he is wrong.  Your program is not required to validate any input other than the sheet size.
2. Determine if the customer wants a set (containing a flat sheet, a fitted sheet, and two pillow cases) or just one of these three components.  The program may allow the customer to enter one word  to indicate whether s/he wants a set or a component, by entering a word such as "set", "flat", "fitted", or "cases".  Altermatively, the program may assume that anything other than the word "set" is one of the components.  For each of the three components, the cost is 40% of the base cost of a set.  Thus, a Queen size fitted sheet or pillow cases costs $24  (40% of $60).
3. Determine the thread count for the sheets.  300 is the standard.  If the customer asks for a thread count that is less than that, deduct 20% from the cost.  If the customer asks for a thread count that is more than 300, add 30% to the cost.  Thus, a Queen size fitted sheet with thread count of 400 costs $31.20 and a Queen size set with thread count 400 costs $78.
4. Determine how many sheets or specified components the customer wants.
5. Ask the customer for the pattern number; there are 64 patterns.  The program should accept any integer number for this value.  All patterns cost the same.
6. Then, display in a clear way the cost of the order, the tax (at 6% sales tax), and the total price is.  Below is a sample output to illustrate a clear display.  Your display does not need to have this exact form; but it must be clear, showing dollars and cents and what the item ordered is.  Here, the item is just referred to as a "fitted-sheet"; you may want to identify specifically "flat-sheet", "fitted-sheet", or "pillow-case-pairs"; but all of these are the same price; so, you may also refer to any of these three generically as "component".

Thus, the output might look like the following instead.

2 Queen size components in pattern 23 with thread count of 400
Cost     $  62.40
Tax      $   3.74
Price    $  66.14

After displaying this report, your program should ask the customer if s/he wants to make another order.  If the customer answers yes, the program must do the steps again.  This must repeat until the customer indicates that there are no more orders.  When that happens, the program must display the total price for all items ordered.

Approximately three days before the project is due, I will give you a list of orders from one customer.  Execute your program on the inputs that I provide and generate the item cost/tax/price and the total price.

Hand in a well-documented printout of your program and a printout of the captured output from the order that I give you, showing the specifications for each item ordered.  Also, copy the program's .cpp file to the handin folder on the P: drive for COSC 110, your section.  Be sure to name the .cpp file after yourself so that it can be distinguished from other student file names.  For example, I would name my file wolfep3.cpp
