Problem about Creating structure

hi all, i've little problem about structure creating, loot at this first..

Code:

---

.......
struct student
{
  int score;
};

struct student *creat()
{
  struct student *head;
  head = (struct student *)malloc (sizeof (struct student));
  scanf("%d", &head->score);  /* my problem is here*/
  return (head);
}

int main()
{
  struct student *pointer;
  pointer = creat();
  ............
}

---

if i don't have a misconception, head is a pointer, it just receives an address from malloc(), and it points to an empty space created by malloc(). but here

Code:

---

head = (struct student *)malloc (sizeof (struct student));
scanf("%d", &head->score);

---

i don't understand : head->score.
did we declare a varible -score while mallocing space?
if not, how can we input a number to it(score)?

Apart from casting the result of malloc (which is poor form in C, see the FAQ), it looks fine.

> i don't understand : head->score.
It's basically the same as
struct student var;
scanf("%d", &head.score);

Except you're dealing with a pointer to a struct rather than a struct (hence the -> in place of .)

Code:

---

scanf("%d", &(head->score));

---

I'm not sure about the precedence so i use extra parentesis.

maybe it interpreted it like:

Code:

---

(&head)->score

---

Which makes no sense.

One of the reasons that the precision of operators was choosen in a way that the code

&head->score

does make sense
