What's the preferred C++ idiom to own a collection of polymorphic objects?

Question

Consider the following classes

class Base {
public:
    virtual void do_stuff() = 0;
};

class Derived : public Base {
public
    virtual void do_stuff() { std::         


        

Answer 1

Actually you cannot store references in STL, only pointers or real values. So T is Base* Try other things you will have your compiler complaining.
