Listing an Array backwards

[Chayio]

I'm trying to create a program that asks for 10 integers, then lists them in an array but backwards. For example the last number you entered shows up first when you run the program, does anyone know how to do this? Any help is appreciated, this is what I have so far:

Turing:

var integers : array 1 .. 10 of int for i : 1 .. 10     put "Input 10 intergers."     var integer : int     get integer         integers (i) := integer end for cls for i : 1 .. 10     put integers (i)     end for

This exact case is listed as one of the examples in the documentation of for, which I suggest you read through : http://compsci.ca/holtsoft/doc/for.html

and just to help you a bit

Turing:

integers (i) := integer

What are you telling the computer here?

Okay that's what it's doing.

run ur print array backwards

instead of having

code:

for i:1..10

have it in decreasing order

code:

for decreasing j : 10 .. 1             put j end for

*srry i forget the code syntax for turing

An easier, and more flexible way to do this though, would be to change what we put the information into, not what information we use.

If there came a situation where you needed it to go from 1 .. 10, but also needed to store information backwards, making the array 10 .. 1 wouldn't work.

you told the computer

Turing:

integers (i) := interger

Why not store it starting at the top and working your way down?

Turing:

integers (upper(integers) - i) := integer

however that would start you at 9 and end you at 0, which doesn't fit your array. So we tell the computer what we want it to do (start at 10 and end at 1)

The way we do this is just through some simple math!

We call this problem solving.

Turing:

integers (upper(integers) - i + 1) := integer

Now everything starts one higher.
