title: Add trailing zeros to an integer
body: <p>I need to add <code>n</code> trailing zeros to an integer.</p>
  
  <p><strong>For example:</strong></p>
  
  <pre><code>n=4
  y=1
  output 10000
  </code></pre>
  
  <p>I used the code below but I need to give an integer value in place of <code>n</code> and that should be converted to number of zeros. Any idea?</p>
  
  <pre><code>n=00 
  y=1 
  printf  "%d$n\n" $y
  </code></pre>
