【求助】请问这个程序通过编译了还是被要求中断是怎么回事

#include<stdio.h>
#include<stdlib.h>
#define Listsize 100

struct Node {
    int data;
    struct Node *next;
};

typedef struct Node ListNode;
typedef struct Node *LinkList;

LinkList CreateCycleList(int n);
void DisplayCycleList(LinkList head);

int main()
{
    LinkList h;
    int n;
    printf("创建一个循环的单链表：\n");
    printf("请输入元素的个数：");
    scanf_s("%d", &n);
    h = CreateCycleList(n);
    DisplayCycleList(h);
    return 0;
}

LinkList CreateCycleList(int n)//创建一个不带头节点的循环单链表
{
    int e;
    LinkList head = NULL;
    ListNode *p, *q;
    int i;
    i = 1;
    q = NULL;
    while (i <= n)
    {
        printf("请输入第%d个元素：", i);
        scanf_s("%d", &e);
        if (i == 1)
        {
            head = (LinkList)malloc(sizeof(ListNode));

        }
        else

            p->data = e;
            p->next = NULL;
            q = p;
        }
        i++;
    }
    if (q != NULL)
