Your code is insanely poorly indented, and you did not tell us the error.
You are also trying to run your code out of the main function.. Why?

Please read a book on C and then come back.

Describe the problem, as it seems that your little program actually doesn't do anything.
I can assert that you copied a half-solved project from someone and try to adopt it for yourself, but that's ok with me, as long as you can prove that you understand what is being done and how you plan to complete the solution.

And the error is?

Yeah that block of code in the middle of nowhere kind of makes it hard to help.
