>Description:
Why cant case lebels use const int variables ?
or
When is a cont int not a const int ?
This behaviour has been around for a while, so i assume its intentional,
but i just cant understand why, it doesnt make sense to me.
I could #define one 1, but i preferable to avoid using defines as they dont do type checking.
Why not allow a const int to be used in case labels ?
>How-To-Repeat:
Compile this gives
test.c:6: case label does not reduce to an integer constant
int main()
{
const int one = 1;
int value = 1;
switch (value) {
case (one):
break;
default:
}
return
}
