Go4Expert - Help in Vectors

I hava a base class and a derived class as below:

Code:

class base

{

//member fns

}

class derived::public base

{

//member fns

}

Now i have created a vector pointer for base class
std::vector<base*> pBase;
And an instance for derived class as well
derived* pDerived = new derived();

My query is :
is it possible to add the derived class object pointer in to the base class vector
i.e. pBase.push_back(pDerived);
Kindly explain me on this.
