title: Unsigned keyword in C++
body: <p>Does the unsigned keyword default to a specific data type in C++?  I am trying to write a function for a class for the prototype:</p>
  
  <pre><code>unsigned Rotate(unsigned object, int count)
  </code></pre>
  
  <p>But I don't really get what <code>unsigned</code> means. Shouldn't it be like <code>unsigned int</code> or something?</p>
