Re: constant in C

[Andrei Bunghez <andrei.bunghez@gmail.com>]

Hi,

Actually that 'const' has no size at all, it is not a variable, has no
address. The preprocessor replaces  const in the source code with
123456789, or whatever its definition is.

For example:

x = const +  3;

will be preprocessed, and the compiler will see:
x = 123456789 + 3;

Therefore you cannot use sizeof(const),  &const etc.


Regards,
Andrei
