Re: Storing base and derived classes in a vector???

I think the trouble is that when you store them, they become animals.
Try the following, which uses std::vector<animal*>list;

#include <iostream>
#include <vector>

class animal {
public:
        animal(){};
        ~animal(){};
        virtual void birth(){
                std::cout << "Gave birth to an animal" << std::endl;
        }
};

class dog : public animal {
public:
        void birth(){
                std::cout << "Gave birth to a puppy" << std::endl;
        }
};

class cat : public animal {
public:
        void birth(){
                std::cout << "Gave birth to a kitten" << std::endl;
        }
};

int main()
{
        animal thing;
        dog max;
        cat lucky;
        
        std::vector<animal*>list;

        list.push_back(&thing);
        list.push_back(&max);
        list.push_back(&lucky);

        for(unsigned char i=0;i< list.size(); i++){
                list[i]->birth();
        }
        return 0;
}
