建立动态链表，然后进行输出
#include <stdio.h>#include <stdlib.h>
#define LEN sizeof(struct student)
struct student
{
long num;
float score;
struct student* next;
};
int n;
struct student* creat(void)
{
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)
{
struct student *p;
p = head;
if(head != NULL)
{
do
{
printf("num:%ld,score:%5.1f\n",p->num,p->score);
p = p->next;
}while(p != NULL);
}
}
int main(void)
{
struct student *pt;
pt = creat();
print(pt);
return 0;
}
