Sciences 303e - Programming
Printing with the print function, and formatting output using tabs
Arithmetic operations with % and / (integer division)
Note: You are not allowed to
use any looping or conditional structures in this program, or any
programming constructs that have not been covered in class.
Write a program that asks the user to enter some amount of
money and prints out
exact change. Your change should involve the fewest possible
number of coins, i.e.
for $.25, the change should consist of one quarter, not two dimes and
Floating-point operations (arithmetic operations with values of type
float) can result in round-off error. You need to make sure that you
do not lose precision in the number of cents in your dollar amount.
Hint: Try multiplying the money amount by 100, then rounding to
the nearest integer (with the round function) and casting this value to
type int to get the number of cents.
cents = int(round(money*100))
Your program should:
be contained in a file called Money.py.
have the following header at the top of your program:
# File: Money.py
# Description: --a description of your program--
# Name: --your name--
# EID: --your eid--
# Course Name: CS 303e
# Unique Number: --your section number--
# Date created:
# Date last modified:
# Slip days used this assignment:
# Total slip days used:
Your program should:
contain and call a main function
use tabs to line up the number of dollars, quarters, etc. in
make use of meaningingful variable names
use comments to document your program
use whitespace and indentation to enhance readability
use the tab escape sequence
For input value 15.34, your output should look exactly like the sample
output above. You will lose credit if it does not. Test your program on
at least 5 different money
amounts, including 15.34, 0.27, and 1.83.
Programs that do not compile will not
receive any credit. Please plan ahead and allow plenty of time
to get help from the TAs, proctors or
instructor if you are having trouble with the program. Please do not
email the course staff the day before the assignment is due if you need
help - it is unlikely that we will respond quickly enough to assist
you. Plan to come to the lab during office hours if you need help.
This program must be submitted by 11 pm on the due date in order to be
considered on time. Please note in your program header how many slip
days you used on this project. If you use slip days, you must email Al
and Jordan when you submit your project. The email subject should be:
"cs 303e: lab 2, late submission". If you do not notify Al and
Jordan, your project will not be graded, so this is important.
This project must be done individually. You may talk to your classmates
about solution approaches, but then you must write your own code.
Reminders - Did you remember to:
do this assignment by yourself?
include comments for readability?
make sure that your program does not produce an
make sure that your output matches the sample output
submit your program in file Money.py using the
turnin program by 11 pm on the due date?
