title: how to assign a value using address?
body: <p>I was asked a question during an C Language interview.
  the question is:</p>
  
  <pre><code>int *point;
  '0x983234' is a address of memory;//I can not remember exactly
  </code></pre>
  
  <p>how could we assign 20 to that memory?
  it looks likes a embedded programming question, can anyone explains me?</p>
