运行不出来。我的删除部分有2个函数，一个是把要删除的数据取出，一个是删除它。请教各位！能判断是代码末尾的那个函数有问题

#include <stdio.h>
#include <stdlib.h>

struct node {
    int value;
    struct node * prior;
    struct node * next;
};

struct node * in_link(void);   //创建一个双向链表
void print_link(struct node * head);
struct node * delete_link(struct node * head, int i);  //删除链表结点
struct node * get(struct node * head, int i);

int main(void)
{
    int i, y;
    struct node * head;
    head = in_link();
    print_link(head);
    printf("你想删除数据在链表的第几个数据: ");
    scanf("%d", &i);
    head = delete_link(head, i);
    print_link(head);
    return 0;
}

struct node * in_link(void)
{
    struct node *head, *temp, *add_temp;
    int n, i;
    printf("您想插入几个数据: ");
    scanf("%d", &n);
    head = (struct node *) malloc(sizeof(struct node));
    if (head == NULL) {
        printf("分配内存失败\n");
        exit (EXIT_FAILURE);
    }
    printf("请输入链表的第1个数据: ");
    scanf("%d", &head->value);
    head->next = NULL;
    temp = head;
    for (i = 2;i <= n;i++) {
        add_temp = (struct node *) malloc(sizeof(struct node)); //动态分配内存空间
        if (add_temp == NULL) {
            printf("内存分配失败\n");
            exit (EXIT_FAILURE);
        }
        printf("请输入链表的第%d个数据: ", i);
        scanf("%d", &add_temp->value);
        add_temp->next = NULL;
        temp->next = add_temp;
        temp = temp->next;
    }
    return head;
}

void print_link(struct node * head)
{
    while (head != NULL) {
        printf("%d ", head->value);
        head = head->next;
    }
    printf("\n");
}

struct node * get(struct node * head, int i)   //将你想删除的数据取出
{
    struct node * temp;
    int j = 1;
    temp = head;
    while (temp != NULL && j < i) {
        temp = temp->next;
        j++;
    }
    printf("%d\n", temp->value);
    return temp;
   
}

struct node * delete_link(struct node * head, int i)    //删除取出的数据，调用了get函数
{
    struct node * temp;
    temp = get(head, i);
    temp->prior->next = temp->next;
    temp->next->prior = temp->prior;
    free(temp);
    return head;
}
