Question: Extend the class linkedListType by adding the following operations: Write a function that returns the info of the kth element of the linked list. If

Extend the class linkedListType by adding the following operations:

Write a function that returns the info of the kth element of the linked list. If no such element exists, terminate the program. Write a function that deletes the kth element of the linked list. If no such element exists, terminate the program.

Provide the definitions of these functions in the class linkedListType

I'm just wanting the code for the sections where it wants me to fill it in in linkedList.h near the bottom. If you need any of my other files please notify me. I had to trim it down to meet the length requirements for chegg, but I don't think I cut out anything you need.

linkedList.h:

#include #include

using namespace std;

//Definition of the node

template struct nodeType { Type info; nodeType* link; };

template class linkedListIterator { public: linkedListIterator(); //Default constructor //Postcondition: current = nullptr;

linkedListIterator(nodeType* ptr); //Constructor with a parameter. //Postcondition: current = ptr;

Type operator*(); //Function to overload the dereferencing operator *. //Postcondition: Returns the info contained in the node.

linkedListIterator operator++(); //Overload the pre-increment operator. //Postcondition: The iterator is advanced to the next // node.
