title: Difference between struct and association
body: <p>I was asked 2,3 questions in an interview which didn't make any sense.</p>
  
  <ol>
  <li><p>Difference between deadlock and thread ( i couldnt compare them )</p></li>
  <li><p>Difference between struct and association ( not comparable again)</p></li>
  </ol>
  
  <p>Are these even valid questions? If yes what would be the answer.</p>
