What is generalization in c++?

Question

OOP

Given the task:

Based on the PersonList class, make a generic List class that can store a list of data of any type.

What should be done in the assignment and what is generalization in c++ ?
I think that in the task you need to write a template class.

Answer 1

You think right.

Answer 2

It seems that here the term "generalized" does not refer to the language. Just follow the example to make the same list, but for any data.
For example, here is a list item:

struct List
{
    struct List * next;
    struct List * prev;
    void * data;
    int dataType;
};

capable of storing data of any type (depending on the dataType, the data pointer will be interpreted differently)
