Class and Inheritance problem

I have a base class with about 5 classes that inherit the one base class. I also have an array of about 1000 base classes that store the class when I create it.

Baseclass BaseClasses[1024];

When I want to store the variable and use it I do this:

BaseClasses[m_iLoc] = storevariable;
Baseclass *pVar = &BaseEnts[m_iLoc];
ClassCar *pVar2 = (ClassCar *)pVar2;
pVar2->Go();

Yet when I try to get some data from the BaseClasses it seems that some of the data is wrong or corrupt. I think this is because the BaseClasses variable is Baseclass only and not one of the other classes. What can I do to fix this?

Your pVar2 is not initialised to anything. You should have
ClassCar* pVar2 = (ClassCar*)pVar;
pVar2->Go();

Thats if I'm understanding what you are actually after

What's pVar1? Shouldn't it just be pVar?

Your objects are of the base class type. You may not cast them to derived class types.
