title: what does "%-9s" does?
body: <p>I am working on a C project and right now using an open source method to be integrated to my code. While going through the code, I got across a <strong>printf</strong> statement that is like this :</p>
  
  <pre><code>printf("%-9s",someString);
  </code></pre>
  
  <p>I understand the format-specifier <strong>%s</strong> but what is <strong>%9s</strong> ?</p>
  
  <p>I tried looking for solutions for this but no success. Any help would be useful. </p>
