C++ : How to create a copy constructor of array that has a pointer?

Question

I have

template <class T>
class arrList: public linearList<T> {
public: 
      arrList() {}
      arrList(const arrList<T>& List);
      ~arrList() {delete[] element; }
protected:
      void indexCheck(int indx) const;
      T* element;
      int arrLength;
      int listSize;
};

And the copy constructor is

template<class T>
inline arrList<T>::arrList(const arrList<T>& List) {
       element = List.element;
       arrLength = List.arrLength;
       listSize = List.listSize;
}

But im not sure if this is correct for T* element, and also if I have to insert the void function in the copy constructor too. I am new to this, and I don't know a lot about it, so any kind of help will be appreciated.
