While
it’s true that a char*
seems to be equivalent to an iterator (in this case)
In all cases. An iterator models pointer behavior. Pointers were
the first iterators. A char* is a random access iterator so can be
used also anywhere you would need a bidirectional, forward, output,
or input iterator.
, I
prefer the iterator/reverse_iterator
much better. For example, if I use an iterator and it
reaches end(), I can do
--it
to get to the last char.
In a
char * model, once I reach
the NULL ptr (at the end of the string), I can’t
back-trackn.
That's not true. You can do the same thing. (I assume you mean the
null terminator, '\0' rather than null pointer.) Just do --ptr to
get to the last char.
