链表中的节点的数据域可以直接插入结构体吗？打印时要怎么写呢？

链表中的节点的数据域可以直接插入结构体吗？如下：

 struct student
{
    int num;
    char name[10];
    int grade;
};
struct stunode
{
    struct student;
    struct stunode * next;
};

如果这样可以的话，打印时要怎样写呢？（见最后几行，事实证明这样写是不可能成功的。。。）求指点

 #include<stdio.h>
#include<stdlib.h>
struct student
{
    int num;
    char name[10];
    int grade;
};
struct stunode
{
    struct student;
    struct stunode * next;
};
main()
{
    int i;
    struct stunode *p,*head;
    struct student h[13]=
    {
        {2,"Lin",92},
        {3,"Zhang",87},
        {4,"Zhao",72},
        {5,"Ma",91},
        {9,"Zhen",85},
        {11,"Wang",100},
        {12,"Li",86},
        {13,"Xu",83},
        {16,"Mao",78},
        {17,"Hao",95},      
        {20,"Lu",82},
        {21,"Song",76},
        {22,"Wu",88}
    };
    head=NULL;
    for(i=0;i<13;i++)
    {
        p=(struct stunode *)malloc(sizeof(struct stunode));
        p->next=head;
        p->stu=h[i];
        head=p;
    }
    for(i=1;i<=12;i++)
    {
        printf("%d  %s  %f\n",head->stu);
        head++;
    }
    printf("%d  %s  %f\n",head->stu);
}

还有一个问题：数组节点是什么意思？
