You have all kinds of { and } that are wrong, and some that are missing. The best way to see them is to go through your code indenting it properly so you can match up { with }.
Posting your code with valid code tags will also help (select all the code and click the code tag icon right-most above the message input area).

I see no closing brace in main(). Also, post your code inside code blocks and indent appropriately, please. It makes it a lot easier to read, and fix.
