Fill in an array from a single formatted keyboard line in C

Question

How can I fill in a double or int array from a single, arbitrarily long, formatted (e.g. space delimited) keyboard line?

For instance:

Enter the elements of the array:
2 32 12.2 4 5 ...

should result in

=> array[0] = 2
=> array[1] = 32 etc.

I know that I can use scanf as follows, but that does not solve my problem, since each element should be entered one by one.

  /* Input data from keyboard into array */

  for (count = 1; count < 13; count++)
  {
      printf("Enter element : %d: ", count);
      scanf("%f", &array[count]);
  }

Thanks.

No. If you leave off the newlines, that would work perfectly fine.

Generally, it is a good idea to avoid using scanf(), though -- it's not the most intuitive function to use (so to say). How about using fgets() to read in the line then parse it using strtof()?

char buf[LINE_MAX];
fgets(buf, sizeof buf, stdin);

char *s = buf, *endp;
int i = 0;
for (i = 0; i < 13; i++) {
    array[i] = strtof(s, &endp);
    s = endp;
}
