今天完成了C语言作业，学习了有关链表的知识；其中部分代码如下：

include

include

using namespace std;

// 定义链表节点
struct Node {
int data;
Node* next;
Node(int d) : data(d), next(nullptr) {}
};

// 定义链表
class LinkedList {
public:
Node* head = nullptr;

// 插入节点
void insert(int k, int d) {
    Node* newNode = new Node(d);
    if (k == 0) {
        newNode->next = head;
        head = newNode;
    } else {
        Node* current = head;
        for (int i = 1; current != nullptr && i < k; i++) {
            current = current->next;
        }
        if (current != nullptr) {
            newNode->next = current->next;
            current->next = newNode;
        }
    }
}

// 删除节点
void remove(int k) {
    if (k == 1 && head) {
        Node* temp = head;
        head = head->next;
        delete temp;
    } else {
        Node* current = head;
        for (int i = 1; current != nullptr && i < k - 1; i++)
            current = current->next;
        if (current && current->next) {
            Node* temp = current->next;
            current->next = temp->next;
            delete temp;
        }
    }
}

// 打印链表
void print() {
    Node* current = head;
    while (current) {
        cout << current->data << " ";
        current = current->next;
    }
    cout << endl;
}

};

int main() {
int n, m, k, d, op;
cin >> n;
LinkedList list;
for (int i = 0; i < n; i++) {
cin >> d;
list.insert(i, d);
}
cin >> m;
for (int i = 0; i < m; i++) {
cin >> op;
if (op == 0) {
cin >> k >> d;
list.insert(k, d);
} else if (op == 1) {
cin >> k;
list.remove(k);
}
}
list.print();
return 0;
}
