title: What is non overloaded pointer to member and overloaded pointer to member?
body: <p>I am reading C++ programming language by Bjarne Stroustrup. I came across the statement in templates section.</p>
  
  <p>A template argument can be a constant expression (§C.5), the address of an object or function
  with external linkage (§9.2), or a non overloaded pointer to member (§15.5).</p>
  
  <p>What is non overloaded pointer to member? Can someone give example?</p>
