title: Input Iterator - Star and Postfix-Operator
body: <p>Is it valid to do this on an input iterator <code>*it++</code> ?</p>
  
  <p>I understand the code as follow, that it dereference the iterator and gives  me the value and then step one ahead. </p>
  
  <p>In the c++ reference the * operator is lower than the postfix operator: <a href="http://en.cppreference.com/w/cpp/language/operator_precedence" rel="nofollow noreferrer">http://en.cppreference.com/w/cpp/language/operator_precedence</a></p>
  
  <p>But I read this style is bad practice. Why?</p>
