If the code doesn't compile, you have to post the compiler diagnostics.
I tried compiling it, and it passed with flying colours. If the program
doesn't link, did you remember to add both files to the link command line?
Anyway, post the error messages you get. The code seems fine, but there
is always a possibility of a compiler malfunction...
