}
};
class tape:public publication
{
float play_time;
public:
void getdata()
{ publication::getdata();
cout<<"Enter Play time: ";
cin>>play_time;

void putdata()
{ publication::putdata();
cout<<"Play time: "<<play_time<<endl;
}
};
void main()
{ 
  clrscr();
  book b;
  tape t;
  b.getdata();
  b.putdata();
  t.getdata();
