13-16th writings (C) of insertion sort

From the pseudocode to one particular language, it always takes some time to get things right in your head.  What were my mistakes?

13th: when I try to print the array, I printed the index.
14th: include <stdio>, rather than <stdio.h>
15th: when I try to print the array, I printed the index.
16th: get it right.

How alarming it is to make the same mistake twice?
