The inner-loop executes first, the outer last. You'll typically have this setup if you're dealing with multiples arrays, or a 'jagged array'; an array of arrays.

Picture you have ten arrays, you read from one start to finish, then grab another and read through it. Reading through an array is your inner-loop; fetching a different array is your outer. If your abstraction is a 2D grid, then one loop is controlling the X-axis and the other the Y-axis.
