c的链表问题请教高手
#include "stdio.h"#include "malloc.h"
#define NULL 0
#define LEN sizeof(struct student)
struct student
{ int num;
float score;
struct student *next;
};
int n;
struct student *creat(void)
{ struct student *head,*p1,*p2;
n=0;
p1=p2=(struct student *)malloc(LEN);
printf("input p1.num,p1.score");
scanf("%d,%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);
scanf("%d,%f",&p1->num,&p1->score);
}
p2->next=NULL;
return(head);
}
main()
{
creat();
}
在输入数字后就不对了,好像是格式不对,看不太懂,请高手给看看。
