title: What is the difference between const double and double const?
body: <p>I came across in a popular C++ blog the following code:</p>
  
  <pre><code>double const x = 1.0;
  </code></pre>
  
  <p>I know that <code>const double*</code> and <code>double* const</code> differ in a way that in the former the value is const while in the other the pointer is const. But what is the difference between <code>double const</code> and <code>const double</code>?</p>
