How can I use “sizeof” in a preprocessor macro?
...d.
Preprocessing directives are evaluated before the source is parsed (at least conceptually), so there aren't any types or variables yet to get their size.
However, there are techniques to getting compile-time assertions in C (for example, see this page).

Does Java have a HashMap with reverse lookup?
