I'm confused! What questions are on-topic for this site?
Simply ask yourself the following questions. To be on-topic the answer must be "yes" to all questions:

Does my question contain embedded code? (a link with the embedded code is still okay)
Did I write that code myself?
**Is it actual code from a project rather than pseudo-code or example code?**
Do I want the code to be good code? (i.e. not code-golfing, obfuscation, or similar)
To the best of my knowledge, does the code work?
Do I want feedback about any or all facets of the code?
