Store derived class objects in base class variables

Question

I would like to store instances of several classes in a vector. Since all classes inherit from the same base class this should be possible.

Imagine this program:

Answer 1

// Below is the solution by using vector vect,
// Base *pBase , and initialized pBase with
// with the address of derived which is
// of type Derived

#include 
#include 

using namespace std;

class Base
{

public:

virtual void identify ()
{
    cout << "BASE" << endl;
}
};

class Derived: public Base
{
public:
virtual void identify ()
{
    cout << "DERIVED" << endl;
}
};

int main ()

{
Base *pBase; // The pointer pBase of type " pointer to Base"
Derived derived;
// PBase is initialized with the address of derived which is
// of type Derived

pBase = & derived;
// Store pointer to object of Base class in the vector:
vector vect;
// Add an element to vect using pBase which is initialized with the address 
// of derived
vect.push_back(pBase);
vect[0]->identify();
return 0;
}
