Is there any difference between List x; and List x();?

• A big difference!
  
  Suppose that List is the name of some class. Then function f() declares a local List object called x:
  
  
  void f()
  {
  List x; // Local object named x (of class List)
  ...
  }
  But function g() declares a function called x() that returns a List:
  
  
  void g()
  {
  List x(); // Function named x (that returns a List)
  ...
  }
