std::istream_iterator::iterator ??

[Mark Lee <cs...@gmail.com>]

I saw strange example in Apache C++ Standard Library User's Guide

http://stdcxx.apache.org/doc/stdlibug/2-3.html
http://stdcxx.apache.org/doc/stdlibug/2-3.html 

std::istream_iterator<int, char>::iterator where = std::find(intstream, eof,
7);

I didn't compile this example.  

I don't understand why it need ::itrerator and why compiler didn't compile
it?

Is it wrong example?

Rogue-wave's documents show this example, too

Yes, it's a typo. I opened an issue to remind us to fix it:
