int a;
protected:

Python provides an inbuilt function 'print' which h automatically generates a line break when it is called, then how can we generate a pattern as :
1
2 2
3 3 3
4 4 4 4
and so on..
using while loop ???

1+2=3
3+3=6

#include <iostream>
using namespace std;
class A{
public:
void f1();
};
class B : public A{
public:
virtual void f1();
}
int main()
{
A * obj = new B;
obj.f1();
}
Ques: can we write virtual before an overridden function from the base class?? if yes which f1() should it call base class f1() or derived class f1()???
