title: How does one execute a no-op in C/C++?
body: <p>for the following:</p>
  
  <pre><code>( a != b ) ? cout&lt;&lt;"not equal" : cout&lt;&lt;"equal";
  </code></pre>
  
  <p>suppose I don't care if it's equal, how can I use the above statement by substituting <code>cout&lt;&lt;"equal"</code> with a no-op.</p>
