Writing a program to print a "Hello, world!" program
<p>I just started reading Accelerated C++ and I'm trying to work through the exercises when I came across this one:</p>

<p><code>0-4. Write a program that, when run, writes the Hello, world! program as its output.</code></p>

<p>And so I came up with this code:</p>

<pre><code>#include "stdafx.h"
#include &lt;iostream&gt;

using namespace std;

int main()
{
    cout &lt;&lt; helloWorld &lt;&lt; endl;

    cin.get();
    return 0;
}

void helloWorld(void)
{
    cout &lt;&lt; "Hello, world!" &lt;&lt; endl;
}
</code></pre>

<p>I keep getting the error <code>'helloWorld' : undeclared identifier</code>. What I figured I was supposed to do is make a function for helloWorld then call that function for the output, but apparently that's not what I needed. I also tried putting <code>helloWorld()</code> in main, but that didn't help either. Any help is greatly appreciated.</p>
