请用C++实现一个链表，把rating.json文件数据读入到链表中,文件里的每条记录包含如下字段信息comment（int）, from,comments,to,score,corp, time

好的，我可以通过以下代码实现一个简单的链表，并将rating.json中的数据读入到链表中。需要注意的是，为了简化代码，我假设rating.json文件中所有记录都包含如下字段信息：comment（int），from，comments，to，score，corp，time。

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

struct Node {
    int comment;
    string from;
    string comments;
    string to;
    int score;
    string corp;
    string time;
    Node* next;
};

class LinkedList {
private:
    Node* head;
public:
    LinkedList() {
        head = nullptr;
    }
    ~LinkedList() {
        Node* current = head;
        while (current != nullptr) {
            Node* next = current->next;
            delete current;
            current = next;
        }
    }
    void addNode(int comment, string from, string comments, string to, int score, string corp, string time) {
        Node* newNode = new Node;
        newNode->comment = comment;
        newNode->from = from;
        newNode->comments = comments;
        newNode->to = to;
        newNode->score = score;
        newNode->corp = corp;
        newNode->time = time;
        newNode->next = nullptr;
        if (head == nullptr) {
            head = newNode;
        }
        else {
            Node* current = head;
            while (current->next != nullptr) {
                current = current->next;
            }
            current->next = newNode;
        }
    }
    void printList() {
        Node* current = head;
        while (current != nullptr) {
            cout << "comment: " << current->comment << endl;
            cout << "from: " << current->from << endl;
            cout << "comments: " << current->comments << endl;
            cout << "to: " << current->to << endl;
            cout << "score: " << current->score << endl;
            cout << "corp: " << current->corp << endl;
            cout << "time: " << current->time << endl;
            cout << endl;
            current = current->next;
        }
    }
};

int main() {
    LinkedList list;
    ifstream ifs("rating.json");
    string line;
    while (getline(ifs, line)) {
        // TODO: 解析json数据并添加到链表中
        int comment;
        string from, comments, to, corp, time;
        int score;
        // 假设数据格式为：{"comment":1,"from":"a","comments":"b","to":"c","score":2,"corp":"d","time":"2022-01-01"}
        sscanf(line.c_str(), "{\"comment\":%d,\"from\":\"%[^\"]\",\"comments\":\"%[^\"]\",\"to\":\"%[^\"]\",\"score\":%d,\"corp\":\"%[^\"]\",\"time\":\"%[^\"]\"}",
               &comment, &from[0], &comments[0], &to[0], &score, &corp[0], &time[0]);
        list.addNode(comment, from, comments, to, score, corp, time);
    }
    list.printList();
    return 0;
}

需要注意的是，这段代码仅是一个简单的示例，实际上读取和解析json数据需要使用json库或手动解析，因此可能需要进行一些修改才能读取rating.json中的数据。
