title: What does the %*s format specifier mean?
body: <p>In some code that I have to maintain, I have seen a format specifier <code>%*s</code> . Can anybody tell me what this is and why it is used?</p>
  
  <p>An example of its usage is like:</p>
  
  <pre><code>fprintf(outFile, "\n%*s", indent, "");
  </code></pre>
