Problem Description

You are to produce a Body Mass Index (BMI) calculator. A BMI is calculated based on a person's height and weight and is used to estimate a healthy body weight for a given height.

As your calculator should be suitable for an international audience it should allow entry of height and weight in meters and kilograms or inches and pounds. The formulae for calculating BMI are:

BMI = weight (kg) / height (m) squared

BMI = weight (pounds) * 703 / height (inches) squared

BMI less than 10 or greater than 35 are considered to be unreliable. Otherwise the interpretation of a BMI is to be according to the table below:

Develop a user friendly product using Visual Basic which will calculate and interpret a BMI for an international audience.

Assume that any input by the user is valid (no error checking of input is required).

You can either assume that a BMI of 25.95, for instance, is outside of the Normal range or you can convert your BMI results to one decimal place using the Round function as described in the lecture notes for the 7th May.

Example Runs

Run 1
Please enter your name ? James
Which units would you like to use (1. Pounds and inches 2. Kilograms and meters)? 1
Please enter your weight ? 176
Please enter your height ? 69

Sections Required

The assignment should be word processed with each page numbered. Suggested left margin 2.5cm, right margin a minimum of 1cm.

The following sections are required (in this order).

1. Title Page

This should contain:

• your name
• subject name
• tutorial group
• tutor's name
• assignment number
• submission date

2. Statement of Authorship

This must contain:

• the standard text for a Statement of Authorship for the Department
• your name
• subject name
• assignment number
• your signature
• date signed

The work will not be marked without a signed statement of authorship.

3. Table of Contents

• List all the major sections in the assignment and the page numbers they occur on.

4. Defining Diagram

• As specified in class and the Defining Diagram Guide.

5. Pseudo Code

• As specified in class and the Pseudo Code Guide.

6. Data Dictionary

• As specified in class and the Data Dictionary Guide. Where possible the data dictionary should appear on the same page as the pseudo code.

7. Desk Check

• As specified in the Desk Check Guide.
• Provide Desk Checks for test run numbers 3 & 5

8. Visual Basic Code

The code should:

• match the logic specified in the Pseudo Code
• the code should be easy to read and understand. It should be
  • well formatted (e.g. correct indentation, a blank line between sections)
  • well commented. This should include comments about the program: program name, purpose, author; comments describing each variable and comments on each section of the program.
  • have meaningful variable names
• have Option Explicit

Copy the code from Access and paste it into your word processed document.

The code listing should:

• be readable
• be in a monospaced (non-proportional) font (Courier New preferred)
• use a font size of 9 or 10pt
• avoid line wrapping (use a small right margin if necessary)

You must include a statement indicating whether the code listed successfully compiled (no syntax errors).

Example statement: "The code listed below compiled successfully." or "The code listed below did NOT compile."

9. Test Plan & Runs

• Using the Test Plan below, cut and paste the table into your document, test the program and fill out the actual result and correct columns of the test plan
• Provide printouts of input and output for test run numbers 2 & 5
• To capture the current Window, ensure that the window is selected (e.g. place the cursor in the desired window) and press Alt+Print Screen. This can then be pasted from the Windows Cut/Paste buffer into the desired document (such as Word).
• To provide a printout of the test runs, capture each window separately. To capture the Immediate window rather than the whole Access window, you need to undock it. To do this Right mouse click on the Immediate window and select Dockable (only if it doesn't already have a tick next to it), the Immediate window should now be a floating separate window that can be captured by itself.

Your runs must be made using the program listed in the previous section. You must include a statement indicating that the program runs are for your program as listed in the previous section.

Example statement: "The program runs below are the output of the program listed in the previous section."
