Lets name the temporary stacks as A and B. They are initially empty, of course.

1) examine the first element of the original stack: let's call it F; if empty go to 6
2) while the top element of A is bigger than F move it to B
3) move F to A (pop from original stack, push to A)
4) move all elements in B to A (pop from B, push to A)
5) go to 1
6) move all elements of A to the original stack
Voila!

Of course you can change the comparison to order the other way around ... and save on stack transfers with some clever tests.

No "copy/paste" programming here.

1) Write the function.
2) Publish it here with a comment about what does not work, the input, expected output and actual output ...
3) Wait for comments from fellow programmers.
4) Inprove your code with the presented suggestion.
5) if still not happy, go back to step 2
6) Finished

What's stackint?
You're creating arrays at line 9

Also, use code tags when posting code ... and lose the line numbers.
