Why isn't syntax highlighting working in a question?

For some reason, the code here is not getting syntax-highlighted. Perhaps it's a problem with my browser/cache or something? Or maybe I'm doing something wrong?

If I remember correctly, usually keywords like class and public get highlighted, this isn't happening in the answer I linked.

Syntax highlighting is dependent on the language. By default that is chosen from the tags that are on the question. However, the question doesn't have any languages tagged. So there's no syntax highlighting.

I've edited your post to manually enable C++ syntax highlighting by adding this:

<!-- language: lang-cpp -->

    You needed a line break before that tag. Fixed it for you. :)
