title: #ifdef _DEBUG in main function
body: <p>Does <code>#ifdef _DEBUG</code> in the main function has any sense if I am working on <em>visual studio 2013</em> ? </p>
  
  <p>If yes, what it is for ?</p>
  
  <pre><code>int _tmain(int argc, _TCHAR* argv[])
  {
  #ifdef _DEBUG
  
  //creating some objects, using  functions etc;
  
  #endif
  }
  </code></pre>
