Unit Award Scheme

shown knowledge of

1. the importance of using meaningful variable and subroutine names throughout their code

demonstrated the ability to

2. use either C#, Python or VB.NET to write a computer program to complete this unit

3. write an appropriately named subroutine that takes a single real number parameter holding the temperature in Fahrenheit and returns the result of the formula celsius = 5 / 9 * (fahrenheit - 32)

4. write an appropriately named subroutine that takes a single real number parameter holding the temperature in Celsius and returns the result of the formula fahrenheit = (celsius * 9 / 5) + 32

5. write a subroutine called 'displayMenu' that has no parameters and displays three menu options, ie '1) Convert from Celsius to Fahrenheit', '2) Convert from Fahrenheit to Celsius' and '3) Exit'

6. use iteration to keep the program running until option 3 has been chosen from the menu

7. display the message 'Invalid option. Try again.' if any value other than 1, 2 or 3 is entered at the menu

8. call the appropriate subroutine to convert the temperature that has been entered by the user when option 1 is chosen

9. call the appropriate subroutine to convert the temperature that has been entered by the user when option 2 is chosen

10. display the result of the conversion using a suitable message.
