我愿意是要输出 输入的全部信息 可是敲出来的代码只能输出第一组数据 是为什么呢?
#include<stdio.h>#include<malloc.h>
#define LEN sizeof(struct Student)
struct Student
{
long num;
float score;
struct Student*next;
};
int n;
struct Student*create()
{
struct Student *head;
struct Student *p1,*p2;
p1=p2=(struct Student *)malloc(LEN);
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;
p1=p2;
p1=malloc(LEN);
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);
}
void main()
{
struct Student *head;
head=create();
print(head);
}
