Question

Problem:
Given the following class definition:
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;}
};

describe/draw the entities and memory usage utilized by the arguments and the return value of the member functions (variables, pointers, references, …).   

For example, a function defined as an additional inline member of the class Node:

node* read_next() {return next;}

Return:

Argument: none

  
As another example, a function (unrelated to this class):
int f(int* p, int& a) {return (2+p*); }   
Return:

Arguments:

Answers:   
a]   
Node(char e, Node* N){element=e;next=N;};   
Return:

Arguments:

  
b] void set_element(char e) {element=e;}   
Return:

Arguments:   

.c] char read_element() {return element;}

Return:   

Arguments:

  
d] void set_next(Node* N) {next=N;}
Return:   

Arguments:

e] char& ref_element() {return element;}

Return:   

Arguments:

  
f] Node*& ref_next() {return next;}
Return:   

Arguments:
