小甲鱼的的第十章的题目，我的死循环了，求分析
#include <stdio.h>#include <malloc.h>
#include <stdlib.h>
#define LEN sizeof(struct student) //
struct student *creat(); //
void print(struct student *head); //
struct student
{
int num;
float score;
struct student *next;
};
int n;
void main()
{
struct student *stu;
stu = creat();
print(stu);
printf("\n\n");
system("pause");
}
struct student *creat()
{
struct student *head;
struct student *p1,*p2;
p1 = p2 = (struct student *)malloc(LEN);
printf("please input the num:\n");
scanf("%d",&p1 -> num);
printf("please intput the score:\n");
scanf("%f",&p1 -> score);
head = NULL;
n = 0;
while(p1 -> num)
{
n++;
if(n == 1)
{
head = p1;
}else
{
p2-> next = p1;
}
p2 = p1;
p1 = (struct student *)malloc(LEN);
printf("please input a num:\n");
scanf("%d",&p1 -> num);
printf("please input the socre:\n");
scanf("%d",&p1 -> score);
}
p2 -> next = NULL;
return head;
}
void print(struct student *head)
{
struct student *p;
printf("There are %d records:\n\n",n);
p = head;
if(head)
{
do
{
printf("ѧoÃÎa:%ldμÄ3鼨Îa:%2.1f\n",p -> num,p -> score);
p = p -> next;
}while(p);
}
}
找到了，哈哈
