Ugh, yeah, you're right. Sorry about that. So the find function does
work correctly, but the for loop is broken.

That appears to be true on my system.

As someone else mentioned, (iter1 == iter2) even though (*iter1 !=
*iter2). It seems as though istream_iterator's are weird; for example,
you can't seem to walk through the stream:
cout << "iter1: " << *iter1 << "\titer2: " << *iter2 << "\t++iter1: "
<< *(++iter1) << "\n";
produces:
iter1: main() iter2: } ++iter1: main()
comp.lang.c++ would be a better place to ask this question (ie. they'll
probably give you a correct answer).
