error C2065: 'cout' : undeclared identifier

Question

I am working on the \'driver\' part of my programing assignment and i keep getting this absurd error:

error C2065: \'cout\' : undeclared identifier

Answer 1

I had the same issue when starting a ms c++ 2010 project from scratch - I removed all of the header files generated by ms and but used:

#include "stdafx.h"
#include 
using namespace std;

int main() {
   cout << "hey" << endl;
   return 0;
}

I had to include stdafx.h as it caused an error not having it in.
