title: Can you compare nullptr to other pointers for order? Is it always smaller?
body: <p>This question is based on code that I found that monitors possible memory leaks, so it contains some code that you probably don't want to see in regular programs like ordering pointers.</p>
  <p>However, I saw that a pointer was set to <code>nullptr</code> and then the pointer was compared to a maximum address. Is it guaranteed by the C++ standard that <code>nullptr</code> is always smaller than other pointers for <code>operator&lt;</code>?</p>
