Can you "walk across" C strings or char pointers (using *(sz+1)) like
you can with arrays. If not, why not? If so, how?

There is essentially no such thing as a C string.
^^^^^^^^^

What is so interesting about "ially no "[1], and how does it contradict
Keith's _completely true_ objection:

You are very naive about natural language.

How so? I'd really like to know what you meant when you wrote that
"There is essentially no such thing as a C string". As I've already
written in this thread, C99 7.1.1p1 clearly defines the term "string":

A _string_ is a contiguous sequence of characters terminated by
and including the first null character.

C uses the term "string" differently than some other languages do, but
I don't see how that affects the discussion. C has strings. Many,
perhaps most, C programs have many strings that exist at execution
time.

There essentially *is* such a thing as a C string. I can think of no
interpretation of your statement that is anything other than just
plain factually incorrect; the presence of the word "essentially" (I
think that's what you meant to emphasize) doesn't change that.

Perhaps I'm missing something. I invite you to explain what your
statement meant, and how it can be interpreted, even figuratively, as
a correct statement.
