例 建立并输出一个简单链表

#include <stdio.h>
struct Student
{
    int num;
    float score;
    struct Student *next;
};
int main( )
{
    struct Student a,b,c,*head,*p;
    a. num=31001;
    a.score=89.5;
    b. num=31003;
    b.score=90;
    c. num=31007;
    c.score=85;
    head=&a;
    a.next=&b;
    b.next=&c;
    c.next=NULL;
    p=head;
    do
    {
        printf("%d  %.1f\n", p->num, p->score);
        p=p->next;
    }
    while(p!=NULL);
    return 0;
}
