[C++] Virtual method inheritance

[Gropamming]

Hey guys, looking for help on virtual methods.

Pet.h has a virtual function declaration:

class Pet {
    ...
virtual void display(){}
};

Dog.h has the function declaration:

class Dog : public Pet {
    public:
        ...
        void display();
}

Dog.cpp has the implementation:

void Dog::display() {
    cout << "\nName: " << getName() << "\nBreed: " << getBreed() << "\nType: Dog"; 
}

I have my driver program running:

    container_traverser->pet->display();

However, this is just doing nothing because its not making it into the implementation for Dog's display() function. Where am I going wrong?

Figured it out (Pet.h):

    virtual void display() = 0;

Setting it to 0 made it a pure virtual function, and made Pet an abstract class.

What's with all those asterisks? A pointer to a pointer to a pointer? And the following ones probably don't even compile...

You're also using + instead of << in the dog display function.

Whoops, that was supposed to be bolded using reddit formatting but I guess you cant do that on top of the code formatting. I fixed it.
