Due Thursday, April 26 at 9:20am on Canvas


Assignment 5.1: Buying Pastries (10 pts)

  • Open a new C++ file called pastries.cpp
  • Add a block comment at the start of your program to include your name and section information:
/*
* Jennifer Parrish
* M/W 9:30-11:20am
*/

  • Imagine you just opened up a bakery called "C++ Pastries."
  • You want to create an online order form for customers to purchase your baked goods.
  • Write a program to collect a customer's order and then print the summary of their order to the screen.
  • Write four variables - 1 for each type of pastry
    • eclairs
    • bear claws
    • croissants
    • cupcakes
  • Name each of your variables according to correct naming conventions.
  • Write a cout statement welcoming the user to your store "C++ Pastries."
  • Write four cout statements asking them how much of each type of pastry they would like to buy.
  • Each cout statement needs to be followed by a cin statement to collect the information for the requested order. (four cin statements)
  • Finally, write a cout statement to print a summary of the customer's order to the screen.
  • Save your file as pastries.cpp and upload it to Canvas.
  • Your output should look identical the following (except the user input will vary).
  • Notice the blank lines. These are important, so don't forget to include them!

Welcome to C++ Pastries!

Assignment 5.2: Mowing Quotes (10 pts)

Your friend is starting a gardening business to mow lawns as a way to help pay for living expenses while going to school. He needs a good way of estimating how much to charge for his services. Here is how he has decided to charge for his work:

  • He's going to charge $12.75 for travel time, no matter how much time it takes him to get to the house.
  • He's going to charge $25.00 per hour he spends cutting the lawn; and his estimates will be based on cutting 2500 square feet (SF) of lawn per hour.
  • He has decided he will round up the estimated number of hours for a job. For example, if someone has a 30 feet by 90 feet lawn (2700 SF), he'll estimate that it's a 2 hour job; but a 2500 SF lawn would only be a 1 hour job.
  • Because he's starting out, he's going to give a 10% discount to all his clients. This discount will apply to both travel time, and to the cost of cutting the lawn.
  • Finally, he needs to charge tax, which is currently 15.3%.
  • Tax is applied after the 10% discount is given to the sum of travel cost and mowing cost.

Project Specifications
  • Write a program to calculate and print a mowing quote for a specific lawn.
  • Name the source code file mowing.cpp and include all your code in this single file.
  • Ask the user for the following inputs (and no other input) in this order as shown in the Example Run below:
    1. width
    2. height

    Assume the user enters only valid numbers.

  • Numbers may not display with exactly two decimal places, which is fine. Display the output using the default formatting and precision for the numbers - do NOT add any formatting statements to the code.
  • Display the number of hours for mowing before the estimate as shown in the Example Run below.
  • Example Run: The input prompts and outputs of the program must look like the following for full credit, including the same order of input and exact wording of the output. For the input shown you must get the same output. However, the output must change properly if the inputs are different:
Enter the size of the lawn's width in feet : 47.5
Enter the size of the lawn's length in feet : 67
To cut a lawn 47.5 by 67 will take 2 hours.

Estimate:
=========
Cutting (2H)    $50
Travel Cost     $12.75
                --------
Subtotal        $62.75
Discount (10%)  - $6.275
Tax (15.3%)     + $8.64067
                ========
Total Owing:    $65.1157
  • In the above example run, the user entered the values shown in italics (for emphasis) to produce the output.
  • Your program does NOT print the characters in italics, nor does the user input appear in italics. Remember to include the $ (dollar sign) characters.
  • The output must line up nicely as shown in the Example Run.
  • After displaying the output, exit the program, and upload it to Canvas.
Hints:
  • Calculating a tax of 15.3% is the same as multiplying by 0.153
  • To round up use the ceil() math function from Lesson 5
