static const vs #define

Question

Is it better to use static const vars than #define preprocessor? Or maybe it depends on the context?

What are advantages/disadvantages for

Answer 1

• A static const is typed (it has a type) and can be checked by the compiler for validity, redefinition etc.
• a #define can be redifined undefined whatever.

Usually you should prefer static consts. It has no disadvantage. The prprocessor should mainly be used for conditional compilation (and sometimes for really dirty trics maybe).
