The heating system in a school should be switched on if the average temperature is less than
17 degrees Celsius (˚C). The average temperature is found from the temperatures in the Art,
English and Music Departments. You are required to write a program that allows the user to
input the three temperatures. The program calculates and displays the average temperature
then displays ‘Heating should be on.’ or ‘Heating should be off.’ as appropriate.
You may practice this task at home, but won’t be able to refer to any notes or files when assessed.

The second question is not related to the database; it's write a line of code to initialize a String variable named strCafe to a Select SQL statement that would select all the fields from a table named Java.
Dim intIndex As Integer = 10
Do While intIndex >= 10
intIndex += 2
It is an infinite loop
The test variable should not be changed within the loop itself
It should have been written as a Do Until loop
