Sequence of Destructor

I don't understand why the sequence of the Destructor of these two classes are different? Does that make any difference?

Code:

---

class Date
{
public:
        Date( int = 1, int = 1, int = 1990 );
        ~Date();
        void print();

private:
        ......
};

class Date
{
public:
        Date( int = 1, int = 1, int = 1990 );
        void print();
        ~Date();

private:
        ...
};

---

It does not make a difference since these are only the declarations. They should however be grouped for better readiblity. Usually the constructor and the desctructor should be right next to each other.
