插入链表节点的问题.求助高手

[fqwetrqr3q2r423423]

建立了一个节点.里面的 a 是4 又在后面插入一个节点.a是56 但是打印出来只有4,没有看到56.请问是哪里出了问题.

#include <stdio.h>
#include <malloc.h>
struct node
{
int a;
struct node *abc;
};
void main()
{
void ceate(int c,struct node **p);
void printflist(struct node *head);
void deletelist(struct node *h);
void insert(struct node *h,int g);
struct node *p;
int b=4;
p=NULL;
ceate(b,&p);

insert(p,56);

//deletelist(p);
printflist(p);




}
void ceate(int c,struct node **p)
{
struct node *p1;


p1=(struct node *)malloc(sizeof(struct node));

p1->a=c;
p1->abc=NULL;
*p=p1;





}
void printflist(struct node *head)
{
while(head!=NULL)
{
printf("%d",head->a);
head=head->abc;
}

}

void deletelist(struct node *h)
{
while(h->abc!=NULL)
{
h=h->abc;
}

free(h);




}
void insert(struct node *h,int g)
{


while(h->abc!=NULL)
{
h=h->abc;
}
h=h->abc;
h=(struct node *)malloc(sizeof(struct node));
h->a=g;
h->abc=NULL;

printf("%d",h->a);



}

[languagec]

void insert(struct node *h,int g)
{

struct node *temp;

while(h->abc!=NULL)
{
h=h->abc;
}
//h=h->abc;
temp=(struct node *)malloc(sizeof(struct node));
temp->a=g;
temp->abc=h->abc;
h->abc=temp;
//h->abc=NULL;

printf("%d",h->a);



}
