How do you define constant array of constant objects in C (not C++)?
I can define
int const Array [] = {
/* init data here */
};
but that is a non-constant array of constant objects.
I could use
int const * const Array = {
/* init data here */
};
and it would probably work. But is it possible do this with array syntax? (Which looks more clean)
An array cannot be "constant" -- what is that even supposed to mean? The array size is already a compile-time constant in any case, and if all the members are constants, then what else do you want? What sort of mutation are you trying to rule out that is possible for a const int[]?
The "double constness" thing applies only to pointers because they can be changed to point to something else1, since the characteristics of arrays are statical by themselves (arrays cannot be changed in size/type/to point to something else) the only const you can apply is to their elements.
int", "pointer to a constant int", "constant pointer to an int", "constant pointer to a constant int".If you want the elements of array do not modify, just use this:
const int Array[];
int constandconst intare completely equivalent expressions, the standard allows both, for the sake of confusing programmers. Gotta love C.
