title: Pointer address C without printf
body: <p>I need to print the address of a pointer (basically recoding <code>%p</code>) but without using <code>printf()</code> and only <code>write()</code> is allowed.</p>
  
  <p>How can I do it? Could you give me some hints?</p>
  
  <p>For example :</p>
  
  <pre><code>printf("%p", a);
  </code></pre>
  
  <p>result :</p>
  
  <pre><code>0x7ffeecbf6b60`
  </code></pre>
