Can you please post the error message also? I think, it would be always helpful to describe a problem.

Closing brace on line 110 corresponds to open brace at line 3 - the body of main() function, so it refuses to parse 'if' operator outside the function body. It's not surprising you messed up the braces given that this code is a unstructured mess of ifs and elses.
