$3.$ In the control for the for loop in find$\_$small$\_$index, index does not start at zero as it does in many of the loops that we have written. It starts at different places, different times that it is called. Why is this?

$4.$ In the while loop in main, start$\_$index only goes up to $8($start$\_$index $<9).$ Explain why the loop does not need to run when start$\_$index equals $9($the last index in the array$).$
