title: Create a pointer for constant memory location address??(C programming)
body: <p><b>The Question</b></p>
  
  <p>1.)Is it possible to declare a pointer variable to reference to the memory address of a constant??I've tried this before <code>pt = &amp;20;</code>(<i>**pt is a pointer variable</i>) but it's not working , so does it mean we can't do it??By the way if it's possible how am i going to work it out??</p>
