{

int rn;

float fees;

public:

abc(int a,float b)

{

rn=a;

fees=b;

}

abc(abc&m)

{

rn=m.rn;

fees=m.fees;

cout<<"\n copy constructor at work";

}

};

void main()

{

clrscr();

float x,y;

cout<<"\n enter the rollno of student";

cin>>x;

cout<<"\n enter the fees of student";

cin>>y;

abc m1(x,y);

cout<<"\n rollno and fees is"<<x<<"and"<<y;

getch();
