title: Initializing strings using pointers
body: <p>What is the difference between:</p>
  
  <pre><code>char arr[20]="I am a string"
  </code></pre>
  
  <p>and</p>
  
  <pre><code>char *arr="I am a string"
  </code></pre>
  
  <p>How is it possible to initialize an array just by using a pointer?</p>
