写一个函数insert,用来向一个动态链表插入结点

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

typedef struct LNode
{
  int num;
  struct LNode *next;
} LNode;

void insert(int n, LNode *node)
{
  //创建新节点
  LNode *newNode = (LNode *)malloc(sizeof(LNode));
  newNode->num = n;

  LNode* next = node->next;

  // node ---> newNode  ---> next
  newNode->next = next;
  node->next = newNode;
}

LNode* creat(int n)
{
  LNode *head, *p;
  head = (LNode *)malloc(sizeof(LNode));
  p = head; //头节点为0 加上头节点共11个节点
  head->num = 0;
  head->next = NULL;
  for (int i = 1; i <= n; i++)
  {
    LNode *newNode = (LNode *)malloc(sizeof(LNode));
    newNode->num = i;
    newNode->next = NULL;
    p->next = newNode;
    p = p->next;
  }
  return head;
}

void printNode(LNode* head)
{
  LNode* p = head->next;
  while (p != NULL)
  {
    printf("num -> %d\n", p->num);
    p = p->next;
  }
}

int main()
{
  LNode *head;
  int n;
  head = creat(10);
  printNode(head);
  printf("请输入需要插入的节点:\n");
  scanf("%d", &n);
  insert(n, head);
  printf("链表的新内容：\n");
  printNode(head);
  return 0;
}
