C++

Please fix my code. It does not match the output and I am not sure how to fix it.

CODE

#include

#include

using namespace std;

typedef struct node{

string data;

void append(string data){

temp->data = data;

temp->next = NULL;

if(size_ == 0 && head == NULL){

(2) Based on Problem P12.12 Turn the linked List of strings implementation into a singly-linked list sList: Drop the previous pointer of the nodes and the previous member function of the iterator. Reimplement the other member functions so that they have the same effect as before. Hint: In order to remove an element in constant time, iterators should store the predecessor of the current node. You can modify the List class provided in the textbook or see modify the implementation of this class posted on ccle (see sample code for lectures 17-20). . Write a program that reads the data from data2.txt into the single-linked list sList. Display the elements of the list and then prompt the user to enter an element for removal. t a loop in which the removal action is until the user requests to quit. Submit the solution as hmw.6.2.cpp. Sample input-output
