title: why we do not use '&' in scanf for char arrray
body: <pre><code>int age;
  char name[10];
  
  scanf("%d", &amp;age);
  scanf("%s", name);
  </code></pre>
  
  <p>In first <code>scanf</code> function we use <code>'&amp;'</code> symbol before age, but in second <code>scanf</code> we don't use <code>'&amp;'</code>
  as it is a char array. Can anybody tell me why is so?</p>
