title: Casting from const int to int in c++
body: <p>Can we cast a <code>const int</code> into an <code>int</code> in C++ without declaring a new variable? 
  This option is available in VS but how can it be used in other compilers such as Xcode, code blocks, etc?</p>
  
  <pre><code>const int a = 5 ;
  int (a) ++ ;
  </code></pre>
