Thread: operator overloading, long error

Hi, I'm, trying to learn operator overloading. I try to compile this and I get an error a page long... Anyone know what's wrong?? thanks

Code:

#include <iostream>

using namespace std;

class Counter
{
public:
  Counter ();
  ~Counter ()
  {
  };
  int GetItsVal () const
  {
    return itsVal;
  }
  void SetItsVal (int x)
  {
    itsVal = x;
  }
  void Increment ()
  {
    ++itsVal;
  }
  const Counter & operator++ ();

private:
  int itsVal;
};

Counter::Counter ():
itsVal (0)
{
};

const Counter &
Counter::operator++ ()
{
  ++itsVal;
  return *this;
}

int
main (int argc, char *argv[])
{
  Counter i;
  cout << "The value of i is " << i.GetItsVal () << endl;
  i.Increment ();
  cout << "The value of i is " << i.GetItsVal () << endl;
  ++i;
  cout << "The value of i is " << i.GetItsVal () << endl;

  Counter a = ++i;
  cout << "The value of a: " << a.GetItsVal () << " and i: " << i.GetItsVal;
  cout << endl;

  return 0;
}
