This is a question on my homework could you help me figure it out?

Write a non-recursive procedure that takes an array and its length and prints its elements in the reverse order. For example, if the array has elements 77, 12, 90, 34, 45, the procedure should print the values 45, 34, 90, 12, 77. Here is the header for the procedure: Procedure printReverse(array[], length)

This would do much better on StackExchange - there's essentially no element of this question that involves mathematics. – Steven Stadnicki Dec 16 '10 at 0:29

@Steven: StackOverflow, you mean. ;) – J. M. Dec 16 '10 at 0:33
So THIS is where all of the terrible questions on StackOverflow originate! – Eric Mickelsen Dec 16 '10 at 4:59

That's a bit unfair, @Eric, – J. M. Dec 16 '10 at 6:25

Ross is correct. Remember that a recursive function is one that calls itself. Writing a for loop as follows involves no such recursion:

for(int i = length - 1; i >= 0; i--) cout << array[i] << " ";

@Ross: Since I can't comment on other posts yet, my code is in C++. Also, I didn't really understand NEWprogrammer's objection to your pseudocode answer so I thought I'd formally write it out in a programming language to show that no recursion was used. – Jason Dec 16 '10 at 1:34

Can you just print array[i] for i counting down from length to 1? Python can do it in one line.

its supposed to be in psuedo code which should be easy but it isnt – NEWprogrammer Dec 16 '10 at 0:27
I would have called mine pseudocode as it is not in any specific language, while Jason's looks like proper C (but I can't be sure). – Ross Millikan Dec 16 '10 at 1:16
