CSCI120A

Introduction to Computer Science and Programming

Spring 2005

Lab Assignment 5

Converting feet and inches to metres and centimetres.

Step 1

Study the following lab specification:

Write a program that will read in a length in feet and inches and will output the equivalent length in metres and centimetres. Use at least three functions: one for input, one or more for calculations, and one for output. Include a loop that lets the user repeat this computation for new input values until the user says he or she wants to end the program. There are 0.3048 metres in a foot, 100 centimetres in a metre and 12 inches in a foot.

Note: you do not type in the code of your program until Step 4.

Step 2

Design an algorithm (the steps to solve the problem). You should have the algorithm approved by your instructor before going on to the next step.

The following web page will help you design your algorithm and pseudocode:

Step 3

Development the pseudocode from your algorithm.

The following web page will help you design your algorithm and pseudocode:

Step 4

Using your pseudocode as a guide, implement your program in the Python language. Use the IDLE GUI to edit and run your program:

Your program should start with a comment block that contains the following information:

# File: lab5.py

# Purpose: Conversion of feet and inches to metres and centimetres

# Programmer: [your name]

# Partner: [your partner's name]

# Course: CSCI120A

# Date: Wednesday 9^th February 2005

# Test data:

Step 5

Test your program by running supplying your own test data. You should test your program with at least 3 sets of test data. Show your test data and results in comments at the top of your program.

Step 6

At the end of the class, save your program file (lab5.py) to your folder on the network in:

CSCI120A\Week06\Lab05

Program points will be based on the following marking scheme:
