Function hiding and delete

Question

Why d.display(1) is not working?

I understand that function hiding comes into picture when we define one simillar function in derived class. I have deleted display(int ,int) version so okay to get it disabled from derived class.

Why display(int) is still not accesible from derived class even though i have used using display from base ?

Answer 1

because using is declared into private specifier list (the default in class declaration)

try to add just before the using a public specifier as

public:
using base::display;
