Re: No warning at implicit removal of const. Was: relearning C: why does an in-place change to a char* segfault?

[string literals not typed const in C even though writing prohibited]

Is there any reason not to always write ...
 
static const char *s = "hello, world";
 
... ?
 
You get all the warnings for free that way.

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"}
