Question

I need to add a few methods to c++’s class.
I’m creating a new class using inheritance called “Super_list” that will inherit all of list’s methods and allow my to add my own.

#ifndef SUPER_LIST_H
#define SUPER_LIST_H

#include "my_containter.h"
#include <list>
using namespace std;

class My_Container;

class Super_list: public list<My_Container>
{
 public:
  void new_func1();
  void new_func2();
  void new_func_3();
};
#endif

This is where I’m using my newly made class:

#ifndef my_container_H
#define my_container_H

#include <list> 
#include "super_list.h"
using namespace std;

class Super_list;

class My_container
{
 private:
  Super_list buddy;
};
#endif

I’m getting a bunch of error relating to the inheritance not being done correctly.
I would appreciate any help or other ideas from completing this task.

Thanks 🙂

I would ask if you really do need to inherit to gain additional functionality. Try using a list as a member of your class. Not only will it make your class easier to change, but it means that code that uses your class won’t care about whether its a list or not.
