So what have you tried so far?

My guess is that if you try to compile this with a C++ compiler, it will work just fine. So, why do you need to convert it further?

(btw, I have my suspicions, I'm no fool)

In any case, you need to show that you tried something. We will not just do a "conversion" to C++ for you.
