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)
...
}
