C++ string cout error

Question

I have have this code, but it's not compiling correctly. When I compile this code

#include "stdafx.h"
#include <iostream>

using namespace std;

int main()
{
    string stringone;
    stringone = "abcdef";
    cout << stringone << endl;
    return 0;
}

The compiler tells me this error:

error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion)

This: error C2679: binary '<<' : no operator found which takes a right-hand operand of type 'std::string' (or there is no acceptable conversion) — AmazingGrace, Aug 14 '13 at 23:07
Don't count on standard headers to include other standard headers. — chris, Aug 14 '13 at 23:08
@RyanTuck I wouldn't be surprised. Different compilers, different implementations of the "standard". It just depends where they've declared `operator<<`. — Zeenobit, Dec 11 '13 at 23:39

You need to use #include <string> as well.

Oh, really? The book I'm using didn't mention that – AmazingGrace Aug 14 '13 at 23:08
@AmazingGrace Which book are you using? – Anderson Green Aug 14 '13 at 23:09

@AmazingGrace, I would be cautious of the book then. Here's a list of some [good ones](http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list). – chris Aug 14 '13 at 23:09
I have the C++ for Dummies – AmazingGrace Aug 14 '13 at 23:10

@AmazingGrace, Yeah, I haven't heard too much praise for that. – chris Aug 14 '13 at 23:10
@AmazingGrace It's the thought that counts. – paddy Aug 14 '13 at 23:20
I'll probably return it and find another book to use – AmazingGrace Aug 14 '13 at 23:21

@chris I think the problem is that c++ is not for dummies – aaronman Aug 14 '13 at 23:22
What book would you recommend? – AmazingGrace Aug 14 '13 at 23:25
@AmazingGrace, Pick one from my link that fits you. – chris Aug 14 '13 at 23:26
