单选题 有如下程序：
#include
using namespace std;
class Point{
int x, y;
public:
Point(int x1=0, int y1=0):x(x1), y(y1){}
int get(){return x+y;}
};
class Circle{
Point center;
int radius;
public:
Circle(int cx, int cy, int r):center(cx, cy),
raaius(r){}
int get(){return center.get()+radius;}
};
int main(){
Circle c(3, 4, 5);
cout＜＜c.get()＜
return 0; ＜/c.get()＜
}
运行时的输出结果是______。
