Procedural C++ programming with Visual Studio 2013

Question

I'm having trouble getting the set-up and namespace to work the way I'm used to with something like Notepad++ of gVIM.

I started an "empty" c++ windows console application project in Visual Studio 2013, and have set up the following test program"

#include <iostream>

using namespace std;

int main() { 
    hello();
    return 0; 
}

void hello() { cout << "hello"; }

When I try anything of this form, I get the following error for every call of function declared outside of main() :

error C3861:'AuxFunction': identifier not found

I don't get any other syntactical or compilation errors.

Is there something I have to change in the project properties (they're all at default except for the empty project and omission of any precompiled headers), or will I have to structure my programs differently if I use Visual Studio?

It's been over a decade since I used VS, but at a glance try adding a prototype for your hello function:

#include <iostream>

using namespace std;

void hello();

int main() { 
    hello();
    return 0; 
}

void hello() { cout << "hello"; }

(more general programming than VS, but the error is VS-specific I guess).
