How to take up to a certain amount of inputs in C

I'm trying to take up to 10 integer inputs and then print out each one. So if the user enters 4 integers the program would print out those 4 and end the program. If they enter 10 it'll print out all 10. If they enter more than 10, it'll only print out the first 10.

Here's what I have so far:

    int array[10];
    int i = 0;

    while(i < 10 && scanf("%d\n", &array[i]) == 1){
      printf("%d ",array[i]);
      i++;

    }

This doesn't quite work, if I enter 3 numbers it'll print out the first 2, and not print out the third until I hit ctrl-D, and will exit when I hit ctrl-D again.

scanf("%d\n" does not return until non-white-space (or EOF) occurs after the int.

To get it to return after the int, use scanf("%d"
