Const variables

[Christian Christmann]

Hi,

is it valid (acc. to ANSI-C 99) to assign an uninitialized
const value a constant afterwards, like

const int constInt;
int main( void )
{
constInt = 10;
return 0;
}

Regards,
Chris

No, it is not. It is OK, however, to initialise it:

const int constInt = 10;

No.

Besides which it isn't even uninitialized. Being in static
storage, it has the value 0.
