c++大学刚入手 求运行结果

#include <iostream.h>
class A
{ private:
   int a,b;
 public:
   A(int i,int j) {a=i;b=j;}
   void move(int x,int y){a=a+x;b=b+y;}
   void show(){cout<<"("<<a<<","<<b<<")"<<endl;}
};
class B:public A
{  private:
   int x,y;
 public:
 B(int i,int j,int k,int l):A(i,j)
 { x=k;y=l;  }
 void show(){cout<<x<<","<<y<<endl;}
 void fun() {move(3,5);}
 void f1(){A::show();}
};
void main()
{  A e(1,2);
 e.show();
 B d(3,4,5,6);
 d.fun();
 d.A::show();
 d.B::show();
 d.f1();
}
求结果 谢谢各位大佬
