程序代码：

//define struct type
typedef struct Lnode {

    int data;
    struct LNode* next;
    
}Lnode;

//creat Link list
void CreatList() {

    //creat Head pointer and Tail pointer
    Lnode** Head;
    Lnode* Tail;

    //creat an empyt Link list
    *Head = (Lnode* )malloc(sizeof(Lnode));
    (*Head)->next = NULL;
    
    Tail = *Head;

    //insert data 
    for (int i = 0; i < 3; ++i) {
        
        //creat new node
        Lnode* P = (Lnode* )malloc(sizeof(Lnode));
        
        //update date domain and pointer domain of new node
        P->data = i;
        P->next = NULL;

        //update pointer domain of before node
        Tail->next = P;

        //update Tail pointer Location
        Tail = P;

    }

}
