Project #5
Due Date: Start of lecture, Thursday, March 9, 2006
Problem Specification:
You and your college roommates frequently order a late-night pizza
snack. There are many pizzerias in the area that deliver to
dormitories. The number of different pizza sizes and prices varies from
pizzeria to pizzeria. Because you are on a tight budget, you would like
to know which size pizza is the best value, so you want to compare as
many different brands and sizes as possible.
To find which pizza is the best value, we must be able to do a
meaningful comparison of pizza costs. Let's use unit price. Pizzas are
sold by size (diameter), measured in inches, so we can define the unit
price of a pizza as its price divided by its area (that is, dollars per
square inch).
Develop a program that computes the unit prices for each of the pizza
sizes and determines the lowest unit price. The number of different
sizes and prices may vary from evening to evening, so this cannot be a
fixed number in the program. It's up to you whether to use a
count-controlled, sentinel-controlled, or flag-controlled repetition;
just make sure it's clear in your documentation and testing.
To lend realism to the project, visit or call one or more of the local
pizza
delivery places, to find out their diameters and prices. Indicate in
your
report whom you called or visited.
What to submit:
You must follow the project preparation and submission documents on the
website.
Your grade will be calculated on a 20-point basis, as follows:
- 6 points -- analysis and design (including algorithm in
structured
English)
- 4 points -- test plan
- 6 points -- correct execution of program according to test plan
- 4 points -- layout and style of program source code
Extra credit:
We'll continue the 2-point bonus for getting an early start. If you
e-mail
your "framework" listing file to Prof. Feldman, and the time stamp on
the
e-mail is no later than 5 PM, Monday, March 6, 2006, you will be
awarded
2 extra project points. The "framework" must be a listing (.txt)
file, with no compilation errors or warnings, that contains the
declared
variables, and a set of comments inserted for the main algorithm steps.
