title: How do I debug a single .cpp file in Visual Studio?
body: <p>Is there any way to debug a single file in Visual Studio.NET? 
  I'm still a noob with C++, but I want to start learning how to get comfortable with the debugger, and as of right now I am writing really small files.</p>
  
  <p>It seems if there is only one source file, it won't let me debug, but the moment I add another one, I can. I am using VS.net 2008.</p>
