(Solved) : Hello Change Linked Node Implementation Code Double Linked List Linked Node Implementation Q35339118 . . . .

hello how can i change this linked node implementation code toDouble Linked List linked node implementation C+

#include”pch.h”

#include <iostream>

using namespace std;

//our node   

struct node

{

       node * next;

       char d;

};

//head and tail pointers

node * head = 0;

node * tail = 0;

//functions declarations

char remove(void);

void append(char);

int find(char);

void traverse(void);

int isempty(void);

//main for testing the access functions

void main(void)

{

       append(‘A’);

       append(‘B’);

       append(‘C’);

       append(‘D’);

       append(‘E’);

       append(‘F’);

       traverse();

       find(‘X’);

       find(‘D’);

       traverse();

       cout << “Removed “<< remove() << endl;

       cout << “Removed “<< remove() << endl;

       traverse();

       //empty the list

       cout << “Remove”;

       while (!isempty())

            cout << remove() << “,”;

       cout << endl;

       traverse();

       find(‘G’);

}

//recives a char element and appends it to the
