title: How to pass arguments to a function through << operator?
body: <p>Is it possible to overload <code>&lt;&lt;</code> operator such that this works?</p>
  
  <pre><code>void f (int f)
  {
  }
  
  int main ()
  {
      f &lt;&lt; 2;
  }
  </code></pre>
  
  <p>What do I need to study for this to work?</p>
