B5: Iteration

In programming, what is iteration?

• The repetition of steps within a program
• The order in which instructions are carried out
• 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 count controlled loop will..

• Repeat code until a condition is met

• Repeat code a specific amount of times

• Repeat code a random amount of times

• None of the above

What am I? This is where instructions are repeated.

• Sequence
• Selection
• Iteration

What am I? This is where a question is asked and depending on the answer, a choice is made.
