I meant to post this in the C forum and not the C++ forum.

Below is the link to a picture of the debug error window

Why am i getting this error. I'm clueless. Thanks :D:D

Your post links are not working for me and a quick scan of the code shows no obvious problem (not to me again at least)

The links don't work. Its better to just use he Advanced Editor (link at the underneath the message editor) and upload the pictures to your thread.

#include <iostream>
#include <string>

Those are c++ header files, not C. You can't compile that program with a C compiler.

Thanks You guys.
