这程序是建立链表
但是为什么只能输入一次数据？？
#include "stdafx.h"
#include
#include "malloc.h"
#define LEN sizeof (struct student)
using namespace std;
struct student
{
long num;
float score;
struct student *next;
};
struct student *creat(void)
{
int n=0;
struct student *p1,*p2,*head;
p1=(struct student*)malloc (LEN);
cin>>p1->num>>p1->score;
head=NULL;
while(p1->num!=0)
{
if(n==0)
{head=p1;p2=p1;}
else
{
p2->next=p1;
p2=p1;
p1=(struct student*)malloc (LEN);
cin>>p1->num>>p1->score;
n=n+1;
}
}
p2->next=NULL;
return(head);
}
