Make this compile

I can't change the integers to public, just ADD something to make this compile


class X
{ private: int x;
public: X(int i){x=i;}
};

class Y{ private: int y;
public: Y(int i){y=i;}
};

int operator +(X &p1, Y &p2){return p1.x+p2.y;};


struct X
{  int x;
 X(int i){x=i;}
};

struct Y{  int y;
 Y(int i){y=i;}
};

int operator +(X &p1, Y &p2){return p1.x+p2.y;};
