title: Xcode 6's Playground feature for Visual Studio or another IDE that uses C++?
body: <p>I have been fascinated by how Apple introduced this playground feature to Swift and Xcode where you can see the results as you program.</p>
  
  <p>Is there an addon/extension for Visual Studio, or a different IDE that does the same kind of feature for C++?</p>
  
  <p>Thank you in advance!</p>
