Thread: template class default constructor problem

I get an error:

request for member `setPairX' in `anotherPoint', which is of non-class type `Pair<float, int> ()()'

which I really do not understand... I only suspect there is something wrong with the default constructor, but I have no clue what.
I have my template in .h file (all declarations and definitions). The part I'm concerned is as follows:

Code:

template< class T1, class T2 > 
class Pair {
          public:
                 Pair();
                 Pair(const T1 &x, const T2 &y) : first(x), second(y) {}
             // ~Pair();
                 void setPairX(const T1 &x);
                 void setPairY(const T2 &y);
                 T1 getPairX() const { return first; }  //inline def
                 T2 getPairY() const { return second; } // inline def
             // void swapPair();
          private:
                  T1 first;
                  T2 second;
};

//definitions for the template
template< class T1, class T2 >
Pair< T1, T2 >::Pair()
{
      first = 0;
      second = 0;
}


template< class T1, class T2 >
void Pair< T1, T2 >::setPairX(const T1 &x)
{
     first = x;
     
}

template< class T1, class T2 >
void Pair< T1, T2 >::setPairY(const T2 &y)
{
     second = y;
    
}

If I call parametrized constructor, everything works fine. But when I call the default one, I get the compiler error I quoted.
That's how I call the default constructor in main:

Code:

    Pair <float, int> anotherPoint();
    anotherPoint.setPairX(1.05);
    cout << anotherPoint.getPairX() << " is first in anotherPoint." << endl;
    anotherPoint.setPairY(4);
    cout << anotherPoint.getPairY() << " is second in anotherPoint." << endl;

Can you tell me what I'm doing wrong?

Also: maybe a stupid question. Do I need to define the destructor? If yes, how?
