title: Formatting: how to convert 1 to “01”, 2 to “02”, 3 to "03", and so on
body: <p>Following code outputs the values in time format, i.e. if it's 1:50pm and 8 seconds, it would output it as 01:50:08</p>
  
  <pre><code>cout &lt;&lt; "time remaining: %02d::%02d::%02" &lt;&lt; hr &lt;&lt; mins &lt;&lt; secs;
  </code></pre>
  
  <p>But what I want to do is (a) convert these ints to char/string (b) and then add the same time format to its corresponding char/string value.</p>
  
  <p>I have already achieved (a), I just want to achieve (b).</p>
  
  <p>e.g. </p>
  
  <pre><code>    char currenthour[10] = { 0 }, currentmins[10] = { 0 }, currentsecs[10] = { 0 };
  
      itoa(hr, currenthour, 10);
      itoa(mins, currentmins, 10);
      itoa(secs, currentsecs, 10);
  </code></pre>
  
  <p>Now if I output 'currenthour', 'currentmins' and 'currentsecs', it will output the same example time as, 1:50:8, instead of 01:50:08.</p>
  
  <p>Ideas?</p>
