title: Are operators faster than functions?
body: <p>While searching for the difference in <code>new</code> and <code>malloc</code>, I came across this statement (<a href="https://www.includehelp.com/cpp-tutorial/difference-between-new-and-malloc.aspx" rel="nofollow noreferrer">source</a>):</p>
  
  <blockquote>
    <p>new is faster than malloc() because an operator is always faster than a function.</p>
  </blockquote>
  
  <p>Are operators always faster than functions? If so, why? I would really appreciate low-level explanations (you can assume basic compiler, SASS, and hardware knowledge).</p>
