Format code properly in post, and post your errors. Also post your makefile or detail how you are compiling and running.

What do you mean?

1. Put special code tags in your post so the code is actually readable.
2. Post the errors you have been getting.
3. Post details on how you are trying to compile and execute the code. What platform? What compiler?
