15 29 C:\Users\dell\Desktop\Untitled1.cpp [Error] declaration of 'Point::Point(const Point&)' outside of class is not definition [-fpermissive]

    void setX(int xx) {x=xx;}
    void setY(int yy) {y=yy;}
    int getX() {return x;}
    int getY() {return y;}
    private:

    Point::Point(const Point&p);
    {
        x=p.x;
        y=p.y;
        cout<<"调用复制构造函数！"<<endl; 
    }
    Point::~Point()
    {
            cout<<"调用构造函数！"<<endl; 
    }
    void funl(Point p)
    {
            cout<<p.getX()<<endl;

        cout<<B.getX()<<endl;
        return 0;
    }

Answer 1

Point::Point(const Point&p);
这一行后面的分号删掉
