title: Does C even have "pass by reference"?
body: <p>I heard that in "c" that there are we can pass the arguments via "call by value" or "call by reference".
  But in one book it's mentioned that there are we can pass the arguments via both way but there is no "pass by reference" but I actually pass the mostly arguments by "pass by reference".</p>
  
  <p>So why it is mentioned "does C even have "pass by reference"?</p>
  
  <p>A detailed description will be greatly appreciated.</p>
