How to pass many integers one at a time without converting to string

I am able to ask a user for an input and insert it to a linked list. So the following will get 1 integer from user:

  printf("Enter an integer: ");
  scanf("%d",&value);
  insert(value); // insert value to linked list

But I want to user to be able to enter many integers (as many as they want). Example: Enter an integer: 5 6 7 8 9 and add 5 to insert then, add 6 to insert and so on.

I read this post "reading two integers in one line using C#" and the suggested answer was to use an array of strings but I don't want to do that. I want every number entered by the user to be entered in a linked list.

main function :

int main(){
   printf("Enter integer(s) : ");
   scanf("%d",&num);
   insert(num);
   return 0;
}

thank you
