Question

So I have a base class with a constructor that takes (T V). I have inherited class obj that has a constructor () I would like to create something like

base * new_list_item = new obj() 

But how to pass to obj base constructor value T val; in C++?

Answer 1

Use the initialiser list:

class obj : public base {
public:
    obj(T v) : base(v)
    {}
};
