Our loop demonstration program contains the following loop: 
For i = 0 To 9
   txtOut.AppendText(strNames(i) & vbCrLf)
Next

What would happen if:
  1. The For statement were changed to:   For i = 0 To 8
  2. The For statement were changed to:   For i = 0 To 10
  3. The For statement were changed to:   For i = 0 To 9 step 2
  4. The For statement were changed to:   For i = 0 To 9 step 14
  5. The For statement were changed to:   For i = 0 To 9 step -1
  6. The assignment statement were changed to:   txtOut.AppendText(strNames(i))
  7. The assignment statement were changed to:   txtOut.AppendText(strNames(j) & vbCrLf)
