title: How to switch between multiple files in UNIX while using VI editor?
body: <p>I'm new to UNIX. I am using VI editor to code for C programming. 
  If I open multiple files at a time using VI editor like,</p>
  
  <pre><code>vi *.c
  </code></pre>
  
  <p>I can edit the first file only. If I press ":wq", it shows me that there are: "6 more files to edit"</p>
  
  <p>How can I switch between those files?</p>
