Running tests in C I'm getting issues:
return_minus_one_for_negative (3 of 3 Assertions)
should_work_for_positive (2 of 2 Assertions)
should_work_for_random
The expression (foldTo(number)) == (solution(number)) is false.
Completed in 0.119257ms

I'm wondering if the way the random number is being passed in C is screwy.

So glad I wasn't the only one who decided to let error handling do the heavy lifting
