设计一个单向链表类模板

好的，以下是一个简单的单向链表类模板的设计：

template<typename T>
class LinkedListNode {
public:
    T data; // 存储节点数据
    LinkedListNode<T>* next; // 存储指向下一个节点的指针

    LinkedListNode(T data) {
        this->data = data;
        this->next = nullptr;
    }
};

template<typename T>
class LinkedList {
private:
    LinkedListNode<T>* head; // 存储指向链表头节点的指针
public:
    LinkedList() {
        this->head = nullptr;
    }

    ~LinkedList() {
        LinkedListNode<T>* current = this->head;
        while (current != nullptr) {
            LinkedListNode<T>* next = current->next;
            delete current;
            current = next;
        }
    }

    void add(T data) {
        LinkedListNode<T>* node = new LinkedListNode<T>(data);

        if (this->head == nullptr) {
            this->head = node;
        } else {
            LinkedListNode<T>* current = this->head;
            while (current->next != nullptr) {
                current = current->next;
            }
            current->next = node;
        }
    }

    void remove(T data) {
        LinkedListNode<T>* current = this->head;
        LinkedListNode<T>* previous = nullptr;

        while (current != nullptr) {
            if (current->data == data) {
                if (previous == nullptr) {
                    this->head = current->next;
                } else {
                    previous->next = current->next;
                }
                delete current;
                return;
            }

            previous = current;
            current = current->next;
        }
    }

    void print() {
        LinkedListNode<T>* current = this->head;
        while (current != nullptr) {
            std::cout << current->data << " ";
            current = current->next;
        }
        std::cout << std::endl;
    }
};

该链表类具有添加节点、删除节点和打印链表等基本功能。其中，节点类`LinkedListNode`包含了节点数据和指向下一个节点的指针；链表类`LinkedList`包含了指向链表头节点的指针，以及添加、删除和打印链表的方法。
