title: Thousand separator in C++
body: <p>I want to create a string in C++ with the following format:</p>
  
  <pre><code>string + numbersWithFormatAndThousandSeparator + string
  </code></pre>
  
  <p>I am not sure whether <code>std::string</code> or <code>snprintf()</code> provides format like that especially the thousand separator. Could someone help me with this?</p>
