C++ class casting - class

Question

Guys I am trying to create an object that can instantiate the other types that inherit it:
#include <iostream>
#include <cstdlib>
class Animal {
public:
char *nome;
Animal (char *nome) {
this->nome = nome;
}
};
class Cachorro : public Animal {
public:
bool enterraOsso;
Cachorro (char* nome, bool enterraOsso) : Animal(nome) {
this->enterraOsso = enterraOsso;
}
};
class Passaro : public Animal {
public:
bool voar;
Passaro (char* nome, bool voar) : Animal(nome) {
this->voar = voar;
}
};
int main() {
Animal *animal;
animal = new Cachorro("Scooby", true);
std::cout << animal->nome << ", " << animal->enterraOsso << std::endl;
animal = new Passaro("Piopio", false);
std::cout << animal->nome << ", " << animal->voar << std::endl;
return 0;
}
The idea is to access the subclass attributes from the superclass also.
I don't know if this is a cast or polymorphism, in Java I know it is possible, but can't do it in C++.
Thank you for all your help.

Answer 1

You can, it is bad design though for a Base class to know about its children:
int main() {
Animal *animal;
animal = new Cachorro("Scooby", true);
Cachorro * c = reinterpret_cast<Cachorro*>(animal);
std::cout << animal->nome << ", " << c->enterraOsso << std::endl;
animal = new Passaro("Piopio", false);
Passaro * p = reinterpret_cast<Passaro*>(animal);
std::cout << animal->nome << ", " << p->voar << std::endl;
}
