title: Get magento 2 custom attribute value
body: <p>I am able to display attribute values using the code below BUT if the attribute is empty it just prints out the word "No"   </p>
  
  <pre><code>&lt;?php echo $_product-&gt;getResource()-&gt;getAttribute('c_address')-&gt;getFrontend()-&gt;getValue($_product); ?&gt;
  </code></pre>
