title: Does variable declaration mean memory allocation?
body: <p>Will it be precise to say that in</p>
  
  <pre><code>void f() {
      int x;
      ...
  }
  </code></pre>
  
  <p>"<code>int x;</code>" means allocating <code>sizeof(int)</code> bytes on the stack?</p>
  
  <p>Are there any specifications for that?</p>
