Container that stores a mixture of base and derived objects?

Question

What is the right thing to do? I know that if the container is of base class value type, then derived object stored is \'sliced\'. If container is of derived class type, the

There is example with std::vector and std::shared_ptr. I think that's what you want.

#include 
#include 
#include 

class Base {
public:
   virtual void foo() {
      std::cout << "base" << std::endl;
   }
};

class Derived : public Base {
   void foo() {
      std::cout << "derived" << std::endl;
   }
};

int main()
{
   std::vector > v;
   v.push_back(std::shared_ptr(new Base));
   v.push_back(std::shared_ptr(new Derived));

   for (auto it : v) {
      it->foo();
   }
}
