Given the following class definition, describe the type of variables used by the arguments and return values of the following member functions (values, pointers, or references):

Example: Node* read_next(){return next;} takes in nothing as argument and returns a pointer of type Node.

class Node {

private:

char element;

Node* next;

public:

Node(char e){element=e, next=NULL;}

Node(char e, Node* N){

{element=e, next=N;}

void set_element(char e) {element=e;}

char read_element() {return element;}

void set_next(Node* N) {next=N;}

char& ref_element() {return element;}

Node*& ref_next() {return next;}

};

a. Node(char e, Node* N){element=e, next=N;}

a. Arguments:

b. Return:
