C++ “Object” class

Question

In Java, there is a generic class called \"Object\", in which all classes are a subclass of. I am trying to make a linked list library (for a school project), and I have managed

Answer 1

There's no generic base class in C++, no.

You can implement your own and derive your classes from it, but you have to keep collections of pointers (or smart pointers) to take advantage of polymorphism.

EDIT: After re-analyzing your question, I have to point out std::list.

If you want a list which you can specialize on multiple types, you use templates (and std::list is a template):

std::list a;
std::list b;

If you want a list which can hold different types in a single instance, you take the base class approach:

std::list x;
