如何用C++从文件中读取数据创建链表

ifstream inputFile("data.txt");

string line;
while (getline(inputFile, line)) {
    // 处理每一行的数据
}

struct Node {
    int data;
    Node* next;
};

Node* head = nullptr;  // 链表头指针
Node* tail = nullptr;  // 链表尾指针

while (getline(inputFile, line)) {
    int data = stoi(line);  // 将字符串转换为整数
    Node* newNode = new Node;
    newNode->data = data;
    newNode->next = nullptr;

    if (head == nullptr) {
        head = newNode;
        tail = newNode;
    } else {
        tail->next = newNode;
        tail = newNode;
    }
}

inputFile.close();
