Code Style Bonus AwardsWas the code particularly impressive in code style for any of these reasons (or more...?)
SummaryOverall there's some good work here. You hit the learning goals. This makes a good start at Ada. One thing I strongly suggest is that you run the code and test things a few times before submission. You would have caught your errors in the input validation then. |

Don't use variable names like a. Instead use meaningful variable names like first_num
