本人新手。。编了一个链表的程序，可是运行不了。。。求解决。。
#include<stdio.h>
#include<malloc.h>
#define NULL 0
struct student
{
    int num;
    struct student *next;
};
void main()
{
    int i;
    struct student *head=NULL;
    struct student *p1,*p2,*p;
    p1=p2=(struct student*)malloc(sizeof(struct student));
    head=p1;
    p2=p1;
    for(i=1;i<=10;i++)
    {
        p1->num=i;
        p1=(struct student*)malloc(sizeof(struct student));
        p1=p2->next;
        p2=p1;
    }
    p2->next=NULL;
    p=head;
    while(p!=NULL)
    {
        printf("%d\n",p->num);
        p=p->next;
    }
}

for(i=1;i<=10;i++)
    {
        p1->num=i;
        p1=(struct student*)malloc(sizeof(struct student));
        p1=p2->next;
        p2=p1;
    }

怎么改啊。。。。

#include<stdio.h>
#include<malloc.h>
#define NULL 0
struct student
{
    int num;
    struct student *next;
};
void main()
{
    int i;
    struct student *head=NULL;
    struct student *p1,*p2,*p;
    head = (struct student*)malloc(sizeof(struct student));
    head->next = NULL;
    p = head;
    for(i=1;i<=10;i++)
    {
        p1=(struct student*)malloc(sizeof(struct student));
        p1->next = NULL;
        p1->num=i;       
        p->next = p1;
        p = p1;
    }
    p=head->next;
    while(p!=NULL)
    {
        printf("%d\n",p->num);
        p=p->next;
    }

}

还是不知道我错在哪。。。。。

还是不知道我错在哪。。。。。

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

typedef struct QueueNode {
    int data;
    struct QueueNode *next;
} QueueNode;


int main(void)
{
    int i;
    QueueNode QueueRoot, *p, *newnode;
    QueueRoot.next = NULL;
    p = &QueueRoot;
   
    for (i = 1; i<=10; ++i)
    {
        newnode = (QueueNode*)malloc(sizeof(QueueNode));
        newnode->data = i;
        newnode->next = NULL;
        p->next = newnode;
        p = p->next;
    }
   
    for (p=QueueRoot.next; p != NULL; p=p->next)
    {
        printf("%d  ", p->data);
    }
    system("pause");
    return 0;
}

那咋办呀
