FIFTH CS 1500 SOLO PROGRAM: Tiling

OBJECTIVE: The purpose of this programming assignment is to get more practice doing top down design of programs with if-else logic, loops, and functions.

THE ASSIGNMENT:

The assignment is to write a program that makes a tile pattern for the user.

INPUT:

The program prompts the user for a width and a number of courses. These numbers are the width and length of the pattern, measured in numbers of whole tiles. In this exercise, there will be no provision for partial tile widths or lengths.

OUTPUT:

The program outputs a pattern having the dimensions given by the user. Look at the sample runs of my solution program to see the appearance the output must have.

For this exercise, your output must be just like the output of the sample. In particular, your tiles must be identical in every way to the tiles in the sample.

THE DESIGN OF THE PROGRAM:

If you wish, you may use this program shell as a starter for your program design.

I expect 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.

I'll discuss some things in class that I think will help you in your efforts to design a solution to this problem.

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

PITFALL:

ASCII tile patterns may contain backslashes and/or double quotes. Remember that you have to escape backslashes and double quotes. For example, the following line of C++ code:

cout << "\\" ;

outputs one backslash.

FORM AND FORMATTING REQUIREMENTS:

Write appropriate function declaration comments for each of your functions. These are comments placed under each function declaration (prototype) to explain the purpose of the function, and to explain what the function does. Read the comments in the example programs in your book, and write similar comments for your functions.

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


  /* PROGRAM Tile Floor Maker */

  /*

  Name:          Gordon Goodguy
  User Name:     goodge
  Course:        CS 1500, Computer Programming I
  Instructor:    John Sarraille
  Date:          January 01, 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 "January 01, 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.)
