A small but important correction: strings are null-terminated, not
NULL-terminated.  NULL is (a macro that expands to) a null pointer
constant.  The terminator for a string is a null character '\0',
sometimes called NUL, not a null pointer.

(The null character is referred to as NULL in some contexts, but
avoiding that term for it is a good way to avoid confusion.)
