But sizeof s is 8 or 4 regardless of the string, while sizeof "some
string" is the length of the string plus 1 (for the null terminator).

static const char s[] = "hello, world"; 
// autosized by initializer

would be a better replacement, or in C99+ if at file scope

(const char[]){"hello, world"}
