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
