char array initialized by string literal

[wij]

I found char array can be initialized by string literal ! Is such coding correct?

--------------------------------------
int main() {
char tnam[]="tmpnamXXXXXX";

int fd=::mkstemp(tnam);
return 0;
}

g++ t.cpp -std=gnu++11

Yes, that's fine.
char modifable[] = "This string can be modiifed";
const char *constant = "This string shouldn't be modified";

That appears to be the C standard, while this is a C++ group.

The languages are not the same.

C++ requires that there is room for a terminating zero.

Yes - I realised this wasn't in clc as soon as I posted it.
My immediate retraction request was, of course, ignored.
Apologies for any confusion caused.
