FIFTH CS 1500 SOLO PROGRAM: Tiled Surface

OBJECTIVE: The purpose of this programming assignment is to get more practice writing and using loops, and designing program with functions.

THE ASSIGNMENT:

Your assignment is to write a program that makes a pattern of tiles for the user.

INPUT:

The program prompts the user for a length and a width. These numbers are the length and width of the pattern, measured in numbers of whole tiles. There does not need to be any provision for partial tile lengths or partial tile widths.

OUTPUT:

The program "outputs a tile pattern" having the dimensions given by the user.

SAMPLE RUNS:

Look the sample runs of my solution program.

THE DESIGN OF THE PROGRAM:

For this assignment, I am not giving you a structure chart to follow. You must create your own design of this program. I am expecting you to employ good principles of top-down design. Substantial credit will be withheld if you do not create a program that uses functions appropriately.

Note: You are NOT allowed to use ANY global variables in this program. You are cautioned to use functions appropriately. That means your program has to contain several functions. I would expect it to have at least five functions, including main. Of course, the number of functions that your program uses depends on the details of your design.

Follow these rules:

A function must do ONE thing well (only one main job).
A function must not contain more than 24 lines of code (including blank lines, and remember lines are not allowed to be more than about 75 characters long).
You are doing something wrong if none of your functions in this program have parameters or return values.

If you want some help with getting started with the design of the program, check out my design suggestions.

Also, you can look at the programs stars.cpp, varStars.cpp, and the development of the checks program to see some C++ code with similarities to the code you need to write.

FORM AND FORMATTING REQUIREMENTS:

At the beginning of your program file put a header comment like this:


  /* PROGRAM Flooring Maker */

  /*

  Name:          Gordon Goodguy
  User Name:     goodge
  Course:        CS 1500, Computer Programming I
  Instructor:    John Sarraille
  Date:          January 1, 1970

  */

Of course, in place of "Gordon Goodguy," you must put your own full name. In place of "goodge" put your user (login) name. In place of the unix epoch date of "January 1, 1970" put the date that you finished the program. Note that the comment delimiters /* and */ are important. They need to be placed correctly or you will get compiler errors.

WHAT TO TURN IN:

You will be sending me two e-mail messages. Please follow these rules:

Always send me e-mail as plain text in the main message body. Never send me attachments.
Always use the exact subject line I specify for each message. (I often get hundreds of e-mail messages in a week. The subject line allows me to find and sort messages.) You will lose a significant number of points on the assignment if you use the wrong subject line.
Be very careful when you send the e-mail. You may use the instructions in your Hello World! lab excercise for guidance. Of course, you will need to make the obvious changes to those directions -- you have to use the correct subject line and filename.
Always send yourself a copy of each e-mail message you send to me, check immediately to see if you receive the message intact, and check within a few minutes to see if you have received e-mail notifiying you about an undeliverable message. You are responsible for sending e-mail correctly.

Here is the list of things you have to turn in:

At the start of class on the due date place the following item on the "counter" in front of me:
- a hardcopy (printed listing) of your program (the C++ source code). Make sure all the code is properly formatted and that it all shows on the paper.
Before midnight on the the due date send me the following by e-mail:
- A copy of the source code (C++ code) with subject line:
  
  CS1500Solo5Source
- a (filtered) script, with subject line:
  
  CS1500Solo5Script
  
  showing the results of several runs of the program illustrating:
  1. its results on all appropriate boundary values,
  2. its results on a representative sample of inputs that are "out of bounds," and
  3. its results on a representative sample of inputs that are well within bounds.

Note that there are no spaces in the subject lines given. It is important that you do not insert any spaces. My e-mail address is:

john@ishi.csustan.edu

WHEN IS THIS ASSIGNMENT DUE?

Look for the due date in the class schedule. (It's at the top level of the class directory.)
