有以下程序： #include ＜iostream＞ using namespace std; class Point’ public: void SetPoint(int x,int y); void Move(int xOff,int yOff); int GetX() return X; int GetY() return Y; private: int X,Y; ; void Point::SetPoint(int x, int y) X=x; Y=y; void Point: :Move(int xOff, int yOff) X+=xOff; Y+=yOff; int main () Point p1; p1.SetPoint(1,2); p1.Move (5, 6); cout＜＜ Point1 is ( ＜＜p1.GetX()＜＜’,’＜＜p1.GetY()＜＜ ) ＜＜end1; return 0; 执行后的输出结果是( )。
A．Point1 is (6,8)
B．Point1 is (1,2)
C．Point1 is (5,6)
D．Point1 is (4,4)
