Error using std::cout in visual cpp console application

Question

I am using visual studio 2013 to build a C++ console application.This is my code which gives an error. I need to write to the console for every function in my application.

// RAT.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"


int _tmain(int argc, _TCHAR* argv[])
{
    std::cout << "Process started";
    return 0;
}

It gives the following error,

Error:namespace "std" has no member "cout"

I dont understand why this basic "cout" gives a such error :( Please help me I am totally confused....

Any good [beginners book](http://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list) or tutorial would tell you what header file is needed. — Some programmer dude, Nov 06 '16 at 04:50
I did that too but it did not work. But after I restart visual studio it worked. Thank you all :) — The Architect, Nov 06 '16 at 05:00
Did you make sure to put that after `#include "stdafx.h"` Remember `#include "stdafx.h"` must come before all other includes or any code. — drescherjm, Nov 06 '16 at 05:07
Well that could be my problem befor. I connot remember whether I put it above or below #include "stdafx.h" . Thanks that is new knowledge :) And please do not downvote. I really had the problem :( — The Architect, Nov 06 '16 at 05:14

You need to place #include <iostream> as your header.

_@Djerdjer_ Your answer is neither correct (should be `#include`), nor even complete (you missed to explain it should be `std::cout`). – πάντα ῥεῖ Nov 06 '16 at 10:31
@πάνταῥεῖ, he is already including "stdafx.h", so I guess he knows how to include headers using #, but you are right I should have put # (because the sample might be generated automatically from visual studio template). In regard to std::cout, he is already using it. – Nov 06 '16 at 13:17
