floating point formats not linked
Abnormal program termination.

为什么要这样？stl 里不时有现成的链表吗？

[oldhunter]

what is the "stl"?
I am studing the Link,so must try it.
can you help me, expert?

[xiaosatan]

你的错误可能在scanf("%d,%f",&p1->num, &p1->num);上，把&p1->score改成&(p1->score)试试。

[oldhunter]

don't successful,it's still alert fllowing:

floating point formats not linked
Abnormal program termination.

[Wolf0403]

you must be using TC2, which should be throw into the garbage bin now.

[daizh]

I perform it successfully using VC++6.0

[xiaosatan]

把scanf("%d,%f",&p1->num, &p1->num);改成scanf("%d",&p1->num);scanf("%f",&p1->num);试试。另外我在“[原创]你知道为什么吗？”也有该问题的讨论。

[darcymei]

there is no problem in your programe
i guess you forget to enter ','between you enter the data to the list

[oldhunter]

To mmlymlymly(mly),If I enter ',' betwwen two number,it throw above error,else must enter number until enter ','.
To xiaosatan(傻蛋),I'll try...

[oldhunter]

#include <malloc.h>
#define NULL 0
#define LEN sizeof(struct student)
struct student
{
int num;
float score;
struct student *next;
};

main()
{
struct student *creat(void);
void print(struct student *);
struct student *p;
p = creat();
print(p);
}

struct student * creat(void)
{
struct student *head,*p1,*p2;
int n=0;
p1 = p2 = (struct student *) malloc(LEN);
scanf("%d", &p1->num);

printf("p1->num was pass.\n");

scanf("%f", &p1->score);

head = NULL;
while(p1->num != 0)
{
++n;
if (n==1)
head = p1;
else
p2->next = p1;
p2 = p1;

p1 = (struct student *)malloc(LEN);
scanf("%d,%f", &(p1->num), &(p1->score));
}

p2->next = NULL;

return head;
}

void print(struct student *p)
{
while(p != NULL)
{
printf("num: %d\tscore: %.2f\n", p->num, p->score);
p = (*p).next;
}
}

It was print "p1->num was pass.",I make sure it hasn't error in line of "scanf("%d", &p1->num);",but it throw error in line of "scanf("%f", &p1->score);",why?

[xiaosatan]

有人说是tc bug。但我想都是结构变量惹的祸。

[xiaosatan]

我想可以这样float temp=0.0;scanf("%f",&temp);p1->score=temp;

[oldhunter]

xiaosatan(傻蛋),you are right.I debug successfully.but this a strangly problem.
