>I've changed your function to use pointer arithmetic...

1. `*(array+index)`

- it's exactly `array[index]`

definition in C and C++

2. `< *lowest`

- it's ineffective (slow indirection) variant of the original code with int lowest

3. `void sort(int*, int)`

- it's absolutely the same function type as `void sort(int[],int)`

;)
