const vs. #define

[Tamas Szekeres]

AFAIK the latter is dedicated to the preprocessor and the value will
be included into the code inline. For example when you define an
expression the evaluation will take place as much as you use your
define.
On the other hand the const variable behaves like a variable (read only).
