title: What is the difference between y=-1 and y=0xFFFFFFFF?
body: <pre><code>y=-1;
  y=0xFFFFFFFF;
  </code></pre>
  
  <p>The question is, is there a difference between these two statements in your code? Explain. If there is a difference, make sure to provide an example.</p>
  
  <p>I was thinking there is no difference, but if the variable y is unsigned, there is a big difference?</p>
