What does the returned value of the strcmp mean?
<p>I know that strcmp returns...</p>

<blockquote>
  <p>A value greater than zero indicates that the first character that does
  not match has a greater value in str1 than in str2; And a value less
  than zero indicates the opposite.</p>
</blockquote>

<p>But what do those positive or negative numbers mean? for example what does 2 mean?</p>
