为什么我的线性链表不能插入节点数据也写不进去数据

[屈工智能科技]

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

//结构体类型
typedef struct snode
{
	int name;
	int asdf;
}link_node;

//链表结点类型
typedef struct node
{
	link_node data;
	struct node *next;
}linknode;


//创建链表
linknode *create_empty_linklist()
{
	linknode *head = NULL;
	head = (linknode *)malloc(sizeof(linknode));
	head->next = NULL;
	return head;
}

//判断链表是否为空
int is_empty_linlist(linknode *head)
{
	return head->next == NULL;
}

//头插法，在头节点之后插入
int insert_head_liklist(linknode *head,int name,int asdf)
{
	linknode *temp = NULL;
	temp = (linknode *)malloc(sizeof(linknode));
	temp->data.name = name;
	temp->data.asdf = asdf;
	temp->next = head->next;
	return 0;
}

//链表输出
int print_linklist(linknode *head)
{
	linknode *p = head->next;
	while(p)
	{
		printf("%d%d",p->data.name,p->data.asdf);
		p = p->next;//找到尾0->next
	}
	printf("\n");
	return 0;
}

//删除节点
int delete_assign_linklist(linknode *head,int data)
{
	linknode *temp = NULL;
	linknode *p = head;

	temp = (linknode *)malloc(sizeof(linknode));

	while(p->next)
	{
		if (p->next->data.name  == data)
		{
			break;
		}
		p = p->next;
	}
	temp = p->next;
	p->next = temp->next;

	free(temp);
	temp = NULL;
	return 0;
}

//主函数
void main()
{   
	linknode *head = create_empty_linklist();
	//插入三个节点
	insert_head_liklist(head,1,2);
	insert_head_liklist(head,2,4);
	insert_head_liklist(head,5,6);
	print_linklist(head);
	system("pause");
}

[真相重于对错]

int insert_head_liklist(linknode *head,int name,int asdf) { linknode *temp = NULL; temp = (linknode *)malloc(sizeof(linknode)); temp->data.name = name; temp->data.asdf = asdf; temp->next = head->next; head->next = temp; return 0; }

你还需要让head->next指向你添加的temp
