I have written a Manchester Encoding encoder / decoder based on my misconception of how it works (whoops).

I made this program in C that tests if a number is prime. I'm as yet unfamiliar with Algorithm complexity and all that Big O stuff, so I'm unsure if my approach, which is a combination of iteration and recursion, is actually more efficient than using a purely iterative method.
