Only if it's big enough to store the terminating null character. For
example, It requires 6 char objects to store 'h', 'e', 'l', 'l', 'o' and
the terminating '\0' character.
char unterminated[5] = "hello";
char terminated1[6] = "hello";
If you don't specify the length, it's automatically set big enough to
include the terminating null character:
char terminated2[] = "hello";
