Hmmm... good question.
I don't think it is.  I think you're falling into a classic C trap.

Let's look at what the value of item and a[item] are in the loop.

               item     a[item]
Iteration 1     -5        1
Iteration 2     -4        2
Iteration 3     -3        3
...

The line you really wanted to write wasn't
  print b / a[item]
but instead was
  print b / item

Later,
Blake.
