title: how to free memory for structure variable
body: <pre><code>typdef struct _structname  
  {  
      int x;  
      string y;  
  } structure_name;
  
  structure_name variable;
  </code></pre>
  
  <p>Now I access <code>variable.x</code> and <code>y</code>. After using it how can i deallocate or free the memory used by <code>variable</code>?</p>
  
  <p>Actually the memory is getting allocated when i am doing <strong>variable.y="sample string"</strong>.So the = operator allocates memory which is causing issue. how can i resolve it now?</p>
