Painter Quote and Receipt Problem
Write a C# assignment program for scheduling a building paint job. Both interior and exterior.
The program will do the following:
Get the following data from the customer:
- Ask the customer to enter his/her name.
- Ask the customer to enter the month number that they want to schedule the paint job for
(Let the customer know the valid entries are 1 – 12).
- Ask the customer to enter the size of the interior and exterior walls (per square feet) that they want to be painted.
- example: interior: 7600
exterior: 6400
- Ask the customer for their credit card number (Let the user know AMEX, VISA, & MC
cards are accepted)
- (Have in mind that AMEX cards are 15 digits, VISA/MC cards are 16 digits)
- example: 312345678912345 (Amex example)
4987654321234567 (Visa example)
Perform the following calculations:
- Calculate the following:
- Total number of gallons(cans) of paint needed for the interior (a whole number)
- Total number of gallons(cans) of paint needed for the exterior (a whole number)
- Total number of gallons(cans) of paint needed altogether (a whole number)
§ Perform your calculations based on the following information:
- Each 1 gallon can of paint can paint 400 SQFT
calculate how many cans (gallons) you need.
- the total cost of interior paint
- the total cost of exterior paint
- the total cost of paint altogether
§ Perform your calculations based on the following pricing:
• Exterior paint is weatherproof and more expensive.
• Price to paint the interior walls: $300.00 (per gallon).
• Price to paint the exterior walls: $600.00 (per gallon).
Create a receipt for the customer that looks as:
- [tab]Date: followed by [Today’s date]
- Code for today’s Date is DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss")
- [tab]Name: followed by [Customer name]
- [tab]Card Number: followed by [Customer credit card number as described below]
- Display the card as six (6) stars followed by the last 4 digits of their card number.
- Example, if card number: 1234567890123456, display: ******3456
- Use Substring.
- [tab]Month Scheduled: followed by [month]
- The month will be displayed in the following format:
§ The 3-letter name of the month followed by a space and then the month the number inside a pair parenthesis.
§ Example: if month = 11, then display: NOV (11)
§ Use enum (if not sure how, replace month name with “???”, ex: ??? (11))
Line 1: [tab]Date: [Today’s Date]
Line 2: [tab]Name: Name
Line 3: [tab]Card Number: ******[Last 4 digits]
Line 4: [tab]Month Scheduled: NOV (11)
<------------ 40 chars ----------->
Only 10 digits of the card number are displayed
Month Scheduled, is the [3-letter Month Name] ([Month Number])
Followed by receipt details.
- A line of space, followed by details.
- Details are as follows:
§ Line 1: [tab]Header row (Type, Area (sqft), Paint (gal), Cost ($) )
§ Line 2: [tab]dashes
§ Line 3: [tab]Interior detail
§ Line 4: [tab]Exterior detail
§ Line 5: [tab]dashes
§ Line 6: [tab]Totals
- The receipt will look something like the following example:
Date: Today's Date
Name: XXXX
Card Number: ******3450
Month Scheduled: NOV (11)
Type Area (SqFt) Paint (Gal) Cost ($)
--------- ----------- ----------- -----------
Interior 7600 19 $5,700.0
Exterior 5500 14 $8,400.0
--------- ----------- ----------- -----------
Total 13100 33 $14,100.0
