In programming, what is iteration?

• The repetition of steps within a program

• A decision point in a program
• Testing a program to make sure it works

Why is iteration important?

• It determines the order in which instructions are carried out
• It allows code to be simplified by removing duplicated steps
• It allows multiple paths through a program
• It ensures the code works correctly

A while loop is used when

• You know how many times you are going to loop

• You want to loop for an unknown number of times, and possibly forever

• You only want to run the code in the loop once

• You see the word while in the problem description

Underline the loop terminating condition in this code

Underline the code the decrements the loop counter

Underline the lines of code that are within the While loop

Explain how we know that line 4 is within the while loop, whilst line 5 is not within the while loop.

use the yellow highlighter on the key you should use to indent code (that you want to be inside your while loop)
