Goals

  1. To do proper array indexing
  2. To use loops in concert with arrays
  3. To declare accumulator variables outside of loops that are used in loops, but whose state persists beyond the loop
  4. To use proper types
  5. To handle boundary cases

Instructions

Fill in a method to compute the mean of an array of ints. Note that even though the inputs are integers, their mean may be a decimal number! For example, the mean of {0, 5, 2, 4} is 2.75. Finally, if an empty array is passed to your method, you should return 0.0. Recall that this is referred to as a boundary case or edge case in testing.
