So I've concluded this afternoon! I took a snippet off one of the newsgroups
that demonstrated push_back for a *vector* of strings, and tried to get it to
work for an array (named "array" oddly enough) of strings; the error message
clued me in:

/home/bernie/cpp/vector2.cpp: In function `int main()':
/home/bernie/cpp/vector2.cpp:30: request for member `push_back' in `array',
which is of non-aggregate type
`basic_string<char,string_char_traits<char>,__default_alloc_template<true,0>

> Stroustrup (page 593, 3rd edition) says string does not have push_back().

That's weird, my copy (same edition) says, "Because string has a
push_back()..." but in context it's clear that that must be a typo fixed in a
later printing. Mine is 5th printing, Jan, 1998. (?)

Now I wonder why that snip is in those STL docs? They are purported to be the
authoritative 'latest stuff', are they not? Oh well, there's a controversy for
another day.

Thanks!
