C循环链表程序出现Process returned -1073741819 (0xC0000005)的问题

Question

我在编写循环链表程序的时候出现Process returned -1073741819 (0xC0000005)的情况，
请问是指针的使用出现问题了吗，还是其他的问题呢？
另外 ListNode* a[N]; //can I create an array using N?这个可以以形参N作为输入创建数组吗？
以下是我的代码，谢谢！

#include <stdio.h>
#include <stdlib.h>
//define a node
typedef struct ListNode
{
    int val;
    struct ListNode* next;
}ListNode;
//construct a linked list Cycle
void makecycle(int N)
{
    int i;
    ListNode* a[N]; //can I create an array using N?
    a[1]->next = a[2];
    a[1]->val = 1;
    for(i = 2; i < N; i++)
    {
        a[i]->next = a[i+1];
        a[i]->val = i;
    }
    a[N]->next = a[1];
    a[N]->val = N;
}
//input needed variables
int main()
{
    int N, A, B, K;
    scanf("%d %d %d %d", &N, &A, &B, &K);
    makecycle(N);
}

供参考：

#include <stdio.h>
#include <stdlib.h>
//define a node
typedef struct ListNode
{
    int val;
    struct ListNode* next;
}ListNode;
//construct a linked list Cycle
void makecycle(int N)
{
    int i;
    //ListNode* a[N]; //can I create an array using N?
    ListNode*a = new ListNode[N];//动态数组
    a[0].next = &a[1];//a[1]->next = a[2];
    a[0].val  = 1;
    for(i = 1; i < N-1; i++)
    {
        a[i].next = &a[i+1];//a[i]->next = a[i+1];
        a[i].val  = i+1;
    }
    a[N-1].next = NULL;//a[N]->next = a[1];
    a[N-1].val  = N;   //a[N]->val = N;

    ListNode *p=a;
    while(p)
    {
        printf("%d ",p->val);
        p = p->next;
    }
}
//input needed variables
int main()
{
    int N, A, B, K;
    scanf("%d %d %d %d", &N, &A, &B, &K);
    makecycle(N);
    
    return 0;
