Is static_cast(…) compile-time or run-time?

Question

Is static_cast(...) something that gets done at compile-time or run-time? I\'ve googled around but I got different answers.

Answer 1

Depends on what you are casting to what else. E.g. static_cast("Hello") ends up calling std::string constructor.

Off the top of my head, I can't think of any case where reinterpret_cast would need to generate actual machine instructions. It's just telling the compiler: take this bit pattern, and believe it to be a value this type.
