split string in ',' C++ : <p>I have a string like this:  </p>

<p><code>17, the day is beautiful , day</code></p>

<p>. 
And I want to split this string in the first ','.
For example I want to take 2 strings. one for <strong><em>17</em></strong> and two <strong><em>for the day is beautiful , day</em></strong></p>
