Iterations & Looping

  • For…Next…Step loops allow you to iterate through a predefined loop of values
  • For…Each loops are used when you don’t know how many iterations you need
  • Do…While and Do…Until loops need three things:
    • A loop control variable
    • A comparison to a sentinel value
    • An exit to the loop
