I have

Answer 1

You could use dynamic_cast<>() to determine the type of your Hero pointer, like so:

Hero *h;
Weapon * i;
// do something assign values
if(dynamic_cast != nullptr)
    h->use(i);

where HeroSubClass is the particular subclass of Hero that you want to check for (Warrior, etc.). If your Hero * is not a pointer to an object of class HeroSubClass, dynamic_cast will return nullptr, if it is, it will return a HeroSubClass *.

Alternatively, you could just check the type of the Weapon * within use() for each HeroSubClass, and perhaps print out something like "Warrior cannot use Staff" if it's an object of the wrong class.
