title: string.find(" ") is not finding spaces
body: <p>I'm trying to find space in a string that a user inputs. I want to use <code>find()</code> from <code>std::string</code> to return the position of the space. </p>
  
  <p>If the input is "Seattle, WA USA", and I want <code>find(" ", 0)</code> to return <code>8</code>, how would I do this? 8th is the space after ","</p>
  
  <pre><code>string inputString = " ";
  cout &lt;&lt; "Enter String to modify" &lt;&lt; endl;
  cin &gt;&gt; inputString;
  int spac = inputString.find(" " , 0);
  </code></pre>
  
  <p>But <code>find()</code> is keep returning <code>0</code>.
  I am not sure why.</p>
