class A {
public:
virtual void Print()=0;
};
class B: public A {
public:
virtual void Print() { cout<< "B"; }
};
class C: public A {
public:
virtual void Print() { cout<< "C"; }
};
int main()
{
Bob2;
Cob3;
A*obj;
obj = &ob2;
obj?>Print();
obj = &ob3;
obj?>Print();
}

using namespace std;
int fun(int);
int main()
{
float k=3;
k = fun(k);
cout<<k;
return 0;
