C ++ creates an array of objects (from different classes)

I need to create an array containing objects from several classes.

Example

class baseClass
{
   //
};

class first : baseClass
{
   //
};

class second : baseClass
{
   //
};

How to create an array that can contain an object firstand / or secondinside it?

This is part of the home task for me, so I have to use arrays, I have already searched and know that this is done with the help of additional libraries and such, but I have no choice here, guys ...
