如何在C++中访问链表中的对象

#include<iostream>
using namespace std;

// 定义链表节点类
class Node {
public:
    int data;
    Node* next;
    Node(int data) {
        this->data = data;
        this->next = NULL;
    }
};

// 在链表中插入节点
Node* insert(Node* head, int data) {
    if (head == NULL) {
        return new Node(data);
    }
    Node* current = head;
    while (current->next != NULL) {
        current = current->next;
    }
    current->next = new Node(data);
    return head;
}

// 访问链表中的对象
void accessObjects(Node* head) {
    Node* current = head;
    int index = 0;
    while (current != NULL) {
        cout << "Object "<< index << ": "<< current->data<< endl;
        current = current->next;
        index++;
    }
}

int main() {
    Node* head = NULL;
    head = insert(head, 10);
    head = insert(head, 20);
    head = insert(head, 30);
    accessObjects(head);
    return 0;
}

Object 0: 10
Object 1: 20
Object 2: 30
