i decided to get rid of the resizeArr() and just call the whole thing here

void populateArr(int arr[], int* i, int *allocated) {
  int val = 0;
  /* loop until the user enters -999 */
  scanf("%d", &val);
  while (val != -999) {
    arr[*i] = val;
    (*i)++;
    if (isFull(*allocated, *i)) {
        int* temp = (int*) malloc(*allocated * sizeof(int));
        makeArrayCopy(arr, temp, *allocated);
        *allocated *= 2;
        free(arr);
        arr = temp;
    }
    /* get next value */
    scanf("%d", &val);
  }
}


// get rid of both scanf
// clean up the array increment
void populateArr(int arr[], int* i, int *allocated) {
  int val;
  while (1) {
    scanf("%d", &val);
    if (val == -999) break;
    arr[(*i)++] = val;
    if (isFull(*allocated, *i)) {
        int* temp = (int*) malloc(*allocated * sizeof(int));
        makeArrayCopy(arr, temp, *allocated);
        *allocated *= 2;
        free(arr);
        arr = temp;
    }
  }
}
