Am I too stupid for programming?

I wrote a C compiler but I don't think I'm smart enough to do anything much serious. Never learnt C++. Did learn Java, OCaml, and C#. How can I know if I'm too stupid for programming? It seems so complex

Even Indians can program. I've even met a couple black programmers before, and they've even started teaching women how to choose, which is pretty close to programming. You aren't to stupid if they can do it.
