修改如下，供参考：

#include <stdlib.h>
#include <malloc.h>
typedef struct Node

    int  num;//序号
    int  data;//密码
    struct Node* next;     //struct LNode* next;
}Node, * LinkList;
int delateQ_data = 0;

LinkList IniList()
{
    LinkList head;
    head = (LinkList)malloc(sizeof(Node));
    if (!head) return NULL;
    head->next = NULL;
    return head;
}
LinkList CreateListR(int a[], int n)
{
    LinkList head = IniList();//LinkList head = IniList;
    LinkList r = head;
    for (int i = 0; i < n; i++)
    {
        LinkList p = (LinkList)malloc(sizeof(Node));
        if (!p) return NULL;  //修改
        p->data = a[i];
