how to create linked list node without specific node names code example

Example 1: how to use a new node c++

struct node(){
  int key; 
  node *next;
  node(x){  
    key = x;
    next = NULL;     
}}
// after you take a input of a linked list .
// creating a new node.
node *temp = new node(key);  // tem pointer pointing towards the new node. 
temp -> next = head; // inserting the mew node in the start .

Example 2: linked list class c++ basic implementation

template<typename T>
class list {
  public:

    struct node {
        T value;
        node* next;
    };

    list() : hd(nullptr), tl(nullptr) {}

    node* head() { return hd; }
    node* tail() { return tl; }

    void insert(node* prior, T value);

    node* at(int i);    

    void erase(node* prior);
    void clear();

    void push_back(T value);
    void pop_back();

    void push_front(T value);
    void pop_front();

    int size();    

  private:
    node* hd, tl;
}
