Why is code indented?

• To group together a function

• To make it easier to identify blocks of code as part of the same logical structure

• To make it easier to read

• All answers are correct

What is data validation?

• Checking that the data entered is wrong

Why are comments used in a program?

• They are required to make the program run

• Comments pad out the program and make it look more professional

• To help security in the code

When should comments be used within a program?

• To help describe what the code and structures are expected to do

• To remind the developer of when lunch is

• To include what tests must be carried out on the code

• Every line, so that you know exactly what is happening
