title: How virtual/abstract methods are displayed in class diagrams?
body: <p>First, I am coming from the Java community, and still a learner in C++.</p>
  
  <p>Please have a look at the following classes</p>

  <p>The second picture shows a sub class of the class "GameObject". It also has a <code>Display()</code> method. There are 5 sub classes of the class GameObject, and they all have this <code>Display()</code> method. So, is this display method in <code>GameObject</code> is a virtual one?</p>
  
  <p>I think it is not abstract virtual (100% virtual)  because the <code>Display()</code> in <code>GameObject</code> displays some texts in <code>GameObject.cpp</code></p>
  
  <p>Anyway, I am not quite sure. Please help!</p>
