错误很多,还需要多加练习啊
#include <stdio.h>
#include <malloc.h>
#define NULL0
#define LEN sizeof(struct student)
struct student
{
long num;
float score;
struct student *next;
};
int n; //全局变量
struct student *creat(void) //定义函数,带回一个指向链表头的指针
{
struct student *head;
struct student *p1,*p2;
n=0;
p1=p2=(struct student *)malloc(LEN); //开辟一个新单元
scanf("%ld,%f",&p1->num,&p1->score);
head=NULL;
while(p1->num!=0)
{
n=n+1;
if(n==1)
head=p1;
else
p2->next=p1;
p2=p1;
p1=(struct student *)malloc(LEN);//不应该是p2
scanf("%ld,%f)",&p1->num,&p1->score);
}
p2->next=NULL;
return (head);
}
void print(struct student *head)
{
struct student *p;
printf("\nNow,these %d records are :\n",n);
p=head;
if(head!=NULL)
do
{
printf("%ld %5.1f\n",p->num,p->score);
p=p->next;
}while(p!=NULL);
}
main()
{ struct student *head;//struct stu笔误吧应该
head = creat();//光调用怎么行
print(head);
}
希望对你能有所帮助。
