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

Compile time. In fact, the compiler doesn't even insert runtime code to check that the result is correct. The compiler does check that the conversion is statically possible, of course. Example: casting from a subclass to a superclass. If the conversion requires invoking a builtin or a casting function, they will be executed at runtime, of course, but there will be no type checking.
