下列程序的运行结果是（ ） #include #include using namespace std; class Point {public: Point; Point; int GetX {return X;} int GetY {return Y;} static int countP; static void GetC {int z; z=sqrt*+*); cout<X=X;this->Y=Y; countP++;} Point::Point { X=p.X; Y=p.Y; countP++;} int Point::countP=0; int main { Point D,*p; Point E; p=&E; void =Point::GetC; ; return 0; }
