using subclass functions

[Hakate]

Hello

is it possible to access a subclass function if i use an array of pointers with the same type as the base class?

Example

BaseClass**b = new BaseClass*[10];

b[0] = new SubClass();

b[0]->//Use a subclass public member function

You can only use functions declared in the base class.
If you need different behaviours for derived classes you have the option of overriding virtual functions.

If you really need to access the derived class specific members, you'll need to cast b[0] to a pointer to SubClass.
