Visual C# | Modular code exercise | Create a function to calculate your BMI
This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.
The answer to the exercise will be included and explained if you attend one of more of the courses listed below!
You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
To avoid having to draw the form needed for this exercise, right-click on the name of your project in Solution Explorer then choose Add --> Existing Item... (you can also press SHIFT + ALT + A to do the same thing).
Choose only the file called frmBMI.cs in the above folder to import it into your project, then edit Program.cs to make this the default form. When you run your application, you should now see this:
You can type in your stats in imperial units, but the button doesn't work yet!
Uncomment the call to show the message box in the code-behind file. Write the BMI function that this calls, using the constants included in the code. Some notes to help you:
- A person's body mass index is their weight in kilograms divided by their height in metres squared.
- There are 12 inches in a foot, and 14 pounds in a stone.
- In an ideal world your BMI should be between 20 and 25, although there are lots of good reasons why this might vary.
Test out your system, then go and have a biscuit!
