title: C - Get pointer adress to string
body: <p>I'm trying to re-code the <code>printf</code> function. I'm stuck on the <code>%p</code> flag.
  As you know, <code>%p</code> flag prints the address of a pointer. The problem is that I would like to get this address in a character string (<code>char *</code>), in order to print it.
  Is there a way to get an address ?</p>
  
  <p>Thank you. </p>
