Question

建立一个有5个结点的单向链表。每个结点包含姓名、年龄和工资。编写两个函数，一个用于建立链表，另一个用

另一个用于输出链表。
要求：1 建立链表的函数名为creat，数据输入和链表建立在函数中实现；
2 输出链表的函数名为output，用以实现creat建立的链表数据的输出；
3 在main函数中调用creat函数和output函数。
模版：（这个不对，只是参考，尽量用这种方法）
#include<stdio.h>
#include<malloc.h>
#define LEN sizeof(struct Student)
struct Student
{
long num;
float score;
struct Student *next;
};
int n;
struct Student *creat()
{
struct Student *head;
struct Student *p1, *p2;
n = 0;
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;
p2 = p1;
p1 = (struct Student *)malloc(LEN);
scanf("%ld, %f", &p1->num,&p1->score);
}
p2->next = NULL;
return(head);
}
void print(struct Student head)
{
strcut Student *p;
printf("\nNow,These %d records are :\n",n);
p = head;
if(head != NULL)
do
{
printf("%d %5.lf\n",p->num,p->score);
p = p->next;
}while(p != NULL);
}
void main()
{
struct Student *head;
head = creat();
print(head);
}

Answer 1

//就在原来的基础上改了一点，按你的模版的话，输入必须int,float的形式（两个数之间有逗号，如果不想要的话，就把输入那儿中间的逗号去掉）
//例如
/*
13,89.90
89,34.34
78,67
0，0
*/最后0结尾
