//--- CLASS DEFINITION

template <class T>

class point

{

public:

point(); // default constructor

point(T valuex, T valuey);

T getx() const;

T gety() const;

void print() const;

void move(T dx, T dy);

point<T> operator + (point<T>); // overload +

private:

Tx;

Ty;

};

Note that the class definition includes the overloading of the + operator. Re-
placingTwith a regular data type such asdoubleyields familiar code.

The class implementation is:

template <class T>

point<T>::point(T valuex, T valuey)

{

x = valuex;

y = valuey;

}

template <class T>

T point<T>::getx() const

{

return x;

}

template <class T>

T point<T>::gety() const

{

return y;

}

template <class T>

void point<T>::print() const

{

cout << x <<""<<y<<endl;

}

template <class T>
