As mentioned before, the updated second edition is ANSI C. That's not C99,
but gcc will be completely happy.

Same with C++. *shrug*.

The fact that you *can* write bad programs doesn't mean you shouldn't learn
a programming language.

"Doesn't do" isn't correct at all. "Doesn't have as a language feature" is
better. And of course, C *does* have strings of a sort.

Anyway, with open source, there are good libraries out there to do both.

It's not *all* altogether a different matter, but generally, yeah, this is
why I advise getting a good book that teachs C++ as an object-oriented
langauge from the ground up rather than as a stepping-stone from C.
