Question

I am trying to understand array declarations, constness, and their resulting variable types.

The following is allowed (by my compiler):

      char s01[] = "abc" ;  // typeof(s01) = char*
const char s02[] = "abc" ;  // typeof(s02) = const char* (== char const*)
char const s03[] = "abc" ;  // typeof(s03) = char const* (== const char*)

Alternatively, we can declare the array size manually:

      char s04[4] = "abc" ;  // typeof(s04) = char*
const char s05[4] = "abc" ;  // typeof(s05) = const char* (== char const*)
char const s06[4] = "abc" ;  // typeof(s06) = char const* (== const char*)

How do I get a resulting variable of type const char* const? The following are not allowed (by my compiler):

const char s07 const[] = "abc" ;
char const s08 const[] = "abc" ;
const char s09[] const = "abc" ;
char const s10[] const = "abc" ;
const char s11 const[4] = "abc" ;
char const s12 const[4] = "abc" ;
const char s13[4] const = "abc" ;
char const s14[4] const = "abc" ;

Thanks

const char *const s15 = "abc";
