“parse error at end of input”, but I'm sure my brackets are correct. (in C)

Question

I'm pretty sure my brackets are matched up correctly, but I'm getting the error "parse error at end of input" No matter how many or few brackets I attach to the end of this program. Since all of the Google results for this error say that the fix lies in the brackets, I'm at a loss for what else it could be. Could someone point out my silly little mistake for me? :)
