Comment

int * fillarr(int arr[], int length){
   for (int i = 0; i < length; ++i){
      // arr[i] = ? // do what you want to do here
   }
   return arr;
}

// then where you want to use it.
int main(){
int arr[5];
int *arr2;

arr2 = fillarr(arr, 5);

}
// at this point, arr & arr2 are basically the same, just slightly
// different types.  You can cast arr to a (char*) and it'll be the same.
