title: Is there any performance cost to always use this pointer in a class
body: <p>Is there any performance cost to dereference <code>this-&gt;</code> pointer
  or is it okay to use.</p>
  
  <p>For example:-</p>
  
  <pre><code>Vertex::Vertex(int data)
  {
      this-&gt;data = data;
      this-&gt;visited = false;
  }
  </code></pre>
