two dimension array?

[erezlevi]

hi,

why can't I get the second dimension values inside $r?

#include <Array.au3>

Dim $a[10][20] = [[1,2,3,4,5,6,7,8,9,0],[11,12,13,14,15,16,17,18,19,20]]

for $i=1 to 10
    $r=$a[][$i]
    MsgBox (0,"this is $r",$r)
Next

A nice mess you've got there erezlevi!

You have declared $a to be a 10 x 20 array then given it values that are 2 x 10.

You have no index for the first element for $a inside the for/next loop.

You are going from 1 to 10 but yu need to go from 0 to 9.

Try this

#include <Array.au3>

Dim $a[2][10] = [[1,2,3,4,5,6,7,8,9,0],[11,12,13,14,15,16,17,18,19,20]]
$J= 1
for $i=0 to 9
    $r=$a[$J][$i]
    MsgBox (0,"this is $r",$r)
Next

[Valuater]

Dim $a[2][10] = [[1, 2, 3, 4, 5, 6, 7, 8, 9, 0], [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]]

For $i = 0 To 1
    For $ii = 0 To 9
        $r = $a[$i][$ii]
        MsgBox(0, "this is $r", $r, 1)
    Next
Next

....... tooooo slow!!!

Lol was $J = 1 really necessary lol?

[herewasplato]

Dim $a[2][20] = [[1, 2, 3, 4, 5, 6, 7, 8, 9, 0], [11, 12, 13, 14, 15, 16, 17, 18, 19, 20]]

For $i = 0 To 9
    $r = $a[0][$i]
    MsgBox(0, "this is $r", $r)
Next

For $i = 0 To 9
    $r = $a[1][$i]
    MsgBox(0, "this is $r", $r)
Next

Val [edit: & others] beat me to it - but here is another way to look at it...

It's surprising how few things in the world are really necessary. I was just too lazy to do what Valuater and herewasplato did .
