Thread: 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)?
