Answer 1

You increment j after you assign a value. Therefore j is 1 too high. J always points to the next array position, which is unassigned. You need to decrement j once after your for loop so it points to the last valid integer. Also, you should define your array as a long int array and int i should also be a long int as well. Once you get into higher numbers, those will fail if they are ints.

Answer 2

Line 33 in the for loop change it from
For(; j>=0; --j)
To
For(--j; j>=0; --j)
(If you want to print them out at least)

Answer 3

Oh yes thank you Odyel and Jerry Hobby
