Subj : Typecasting question

Hi,

Let's say I have something like this:

    class X{};
    class Y: public X
    {
        public:
            int aValue;
    };

    X    *objects[10];

I have a few questions about this. I'm not very skilled in C++ so is this 
code correct:
    objects[0] = new Y();

From what I know, the compiler takes this code and I can make use of its 
overloaded functions. But the objects array is pointing to X classes. And 
when I want to call a property from the Y class, I don't know how to do 
this. I tried typecasting but it didn't work:
    someValue = (X)objects[0]->aValue;

aValue isn't a member of the X class, how to tell that objects[0] is 
actually an instance of class Y?

Greetings,
Rick
