comparing arrays for creating a new array with data (for-next problem)

roeselpi · November 29, 2020

hello again,

it has been a long time since i have been here and a long time since i last used autoit. ever so often when the time allows me to, then i follow up on an idea that i had a long time ago. i have done all the work on paper but now it is up to writing it in autoit and i keep stumbling over many little issues here and there. sometimes after a few days i will try again and get a step further but sometimes it just will not help no matter how long i try and think about a solution. for most of you it will be the basics but for me it is not all that easy, but at least i give it a try.

right, down to business:

here is my code:

#include <MsgBoxConstants.au3>
#include <StringConstants.au3>
#include <Array.au3>
#include <String.au3>

;
; PART 1: define replacements and check with msgbox
;

    Global $y, $z
    $y = "Yes"
    $z = "No"
    MsgBox(0,"replacements", $y & @CRLF & $z) ;the replacements in a message box

;
; PART 2: set the texts and check via console and msgbox
;

    Global $my1string = "abab" ;the first specified text
    MsgBox(0,"my1string", $my1string) ;the message box to output the first specified text

    Global $my2string = "icic" ;the second specified text
    MsgBox(0,"my2string", $my2string) ;the message box to output the second specified text

;
; PART 3: transform the strings to individual arrays
;

    $my1array = StringSplit($my1string, "")
    $my1array[0] = ""
    _ArrayDelete($my1array, 0)
    _ArrayDisplay($my1array, "my1array") ;the display of the first specified array

    $my2array = StringSplit($my2string, "")
    $my2array[0] = ""
    _ArrayDelete($my2array, 0)
    _ArrayDisplay($my2array, "my2array") ;the display of the first specified array

;
; PART 4: create an empty array for filling
;

    Global $OutputArray[4]
    $OutputArray[0] = ""
    _ArrayDisplay($OutputArray, "OutputArray") ;the display of the first specified array

;
; PART 5: compare & fill empty OutputArray with data after evaluation
;

    Global $i, $j, $k

    For $i = 0 to UBound($my1array) -1
        For $j = 0 to UBound($my2array) -1
            For $k = 0 to UBound($OutputArray) -1
                If $my1array[$i] = "a" And $my2array[$j] = "i" Then
                $OutputArray[$k] = $y
                Else
                $OutputArray[$k] = $z
                EndIf
            Next
        Next
    Next

_ArrayDisplay($OutputArray, "OutputArray") ;the display of the Newly filled Array

In "Part 2" i make a string that is converted to an array in "Part 3" ... Now, I know that "a" and "i" are always in the exact same spot in both arrays and so i wanted to compare this and make a further array to document my findings by saying "yes" or "no" ... however my new array keeps saying just "no" allthough i can clearly see and know that it should say:

yes
no
yes
no

my guess is that there is something wrong within my for-loops and that the counting is somehow "off" i guess that when the first for-loop is finished it reaches the second whilst the second for-loop is checking the first which would explain why it always says "no" instead of seeing the obvious.

so my question would be: what is wrong with my for-loop? or where am i making an error that ultimately gives me the wrong results?

help is much appreciated.

kind regards

Hi roeselpi,

if your arrays are always the same size (and as you say the strings are in the same index position, I consider this as given):

Global $i
For $i = 0 To UBound($my1array) - 1
    If $my1array[$i] = "a" And $my2array[$i] = "i" Then
        $OutputArray[$i] = $y
    Else
        $OutputArray[$i] = $z
    EndIf
Next

Your nested loops were running to all 3 arrays asychnronous - at first k walks from 0 to ubound while i+j are 0, then k again while j=1 and i=0 etc.

FYI, there is no need to declare variables used as index in a For...Next loop. AutoIt will auto-declare it Local. As it is usually the case, those variables should not have a Global scope.

pixelsearch · November 29, 2020

Hi Nine,
I once had an issue with this behavior, i.e. "the variable used as index in a For...Next loop will be created automatically with Local scope"

Here are the parts of the script concerned with this (minor) issue. First what didn't work :

Global $aListe_img, $iNum_img = 0 ; declared outside of functions
...

Func Treatment() ; called from main GUI several times (depending on user actions)
    AdlibRegister("AdlibProgressBar", 1000) ; each second
    For $iNum_img = 1 To $aListe_img[0]
        ...
    Next
    AdlibStop()
EndFunc 

Func AdlibProgressBar()
    ; Issue because $iNum_img will always be equal to 0
    ProgressSet($iNum_img / $aListe_img[0] * 100, _
        $iNum_img & " / " & $aListe_img[0])
EndFunc

Func AdlibStop()
    AdlibUnRegister("AdlibProgressBar")
    ProgressOff()
EndFunc

Now what's working :

Global $aListe_img, $iNum_img = 0 ; declared outside of functions
...

Func Treatment() ; called from main GUI several times (depending on user actions)
    AdlibRegister("AdlibProgressBar", 1000) ; each second
    For $iNum_img_local = 1 To $aListe_img[0]
        $iNum_img = $iNum_img_local ; <==========================
        ...
    Next
    AdlibStop()
EndFunc 

Func AdlibProgressBar()
    ; Ok because $iNum_img will be incremented correctly
    ProgressSet($iNum_img / $aListe_img[0] * 100, _
        $iNum_img & " / " & $aListe_img[0])
EndFunc

Func AdlibStop()
    AdlibUnRegister("AdlibProgressBar")
    ProgressOff()
EndFunc

I don't know if It could have been scripted differently but at least it works. Maybe it could help anyone having the same issue

changes in old code, variable was initially named $iNum_img (iirc)

Nine · November 29, 2020

Yep, always a tricky thing to name Global and Local variables the same name. You have to be very careful, otherwise a bug can happened so quickly.

roeselpi · November 29, 2020

hello,

ok, first of all thanks @Marc for the simple solution and explaination. works beautifully. and is perfect for my needs.

second of all thanks @Nine for a explaination where i was at loss for knowledge. i thought global must be used if data needs to be processed or used everywhere within the file and not just in a locally based area like the for-loop. that is why i always tend to use global when in doubt. probably not the best idea but sofar no conflicts within my little experiments.

i think i can now get onto another problem that needs to be addressed after using the search and trying to find a solution first.

thanks a lot for the help.

kind regards

Also, the opposite can happen, no variable created when you think it has:

For $n=1 To 100
;then somewhere way below nested 
;;;;;;;
;;;;;;;

   Local $n
   For $n=1 To 100
   Next
Next

Another two cents:

You dont need to clear an array element before deleting the element... or you could eliminate the two lines of code

completely by using the 3rd parameter ($STR_NOCOUNT) in StringSplit.

roeselpi · December 1, 2020

wow. never saw that $STR_NOCOUNT in the help file ... or should i rather say, i just clearly missed it. implemented it straight away. thanks @dmob

roeselpi · December 8, 2020

hello again,

now ther is an issue here. ... there must be some way to simplify this somehow, because as my example will show only five different things will result in 25 entries. imagine i had 100 different entries then it would result in 10000 if ... then tasks in one single for-loop. ... example:

Global $01, $02, $03, $04, $05
$01 = "Cable01"
$02 = "Cable02"
$03 = "Cable03"
$04 = "Cable04"
$05 = "Cable05"

Global $my1array[5] = ["Set1", "Set2", "Set3", "Set4", "Set5"]
Global $my2array[5] = ["Mod1", "Mod2", "Mod3", "Mod4", "Mod5"]
Global $OutputArray[5] = ["#", "#", "#", "#", "#"]

For $i = 0 To UBound($my1array) - 1
        If $my1array[$i] = "Set1" And $my2array[$i] = "Mod1" Then $OutputArray[$i] = $01
        If $my1array[$i] = "Set1" And $my2array[$i] = "Mod2" Then $OutputArray[$i] = $02
        If $my1array[$i] = "Set1" And $my2array[$i] = "Mod3" Then $OutputArray[$i] = $03
        If $my1array[$i] = "Set1" And $my2array[$i] = "Mod4" Then $OutputArray[$i] = $04
        If $my1array[$i] = "Set1" And $my2array[$i] = "Mod5" Then $OutputArray[$i] = $05
        
        If $my1array[$i] = "Set2" And $my2array[$i] = "Mod1" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set2" And $my2array[$i] = "Mod2" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set2" And $my2array[$i] = "Mod3" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set2" And $my2array[$i] = "Mod4" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set2" And $my2array[$i] = "Mod5" Then $OutputArray[$i] = $...
        
        If $my1array[$i] = "Set3" And $my2array[$i] = "Mod1" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set3" And $my2array[$i] = "Mod2" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set3" And $my2array[$i] = "Mod3" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set3" And $my2array[$i] = "Mod4" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set3" And $my2array[$i] = "Mod5" Then $OutputArray[$i] = $...
        
        If $my1array[$i] = "Set4" And $my2array[$i] = "Mod1" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set4" And $my2array[$i] = "Mod2" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set4" And $my2array[$i] = "Mod3" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set4" And $my2array[$i] = "Mod4" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set4" And $my2array[$i] = "Mod5" Then $OutputArray[$i] = $...
        
        If $my1array[$i] = "Set5" And $my2array[$i] = "Mod1" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set5" And $my2array[$i] = "Mod2" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set5" And $my2array[$i] = "Mod3" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set5" And $my2array[$i] = "Mod4" Then $OutputArray[$i] = $...
        If $my1array[$i] = "Set5" And $my2array[$i] = "Mod5" Then $OutputArray[$i] = $...
    Next

if that is only 5 then it would be 5x5 ... 25 possible comibnations

and if you factor in the 5 $01-$05 then it boils down to 5x5x5 ... 125 possible comibnations in one for loop. i have aprox 100 entries of each parameter.

that means the for-loop would be 100x100x100 entries long ... 1 million if ... and ... then terms in a just one for loop. is that possible at all? i guess that would take forever?

would it be possible to make the for loop into a fuction and outsource it to a secondary file?

i think my plan just went from easy and small to impossible and large.

i would need to know if i should continue or give up. if the programm can not handle 1.000.000 'ifs' in a for-loop at least once in an adequate amount of time, then there is no use in continuing the process.

any thoughts?

JockoDundee · December 8, 2020

From a purely functional point of view, something like this could collapse the logic as you requested.

Global $01, $02, $03, $04, $05
$01 = "Cable01"
$02 = "Cable02"
$03 = "Cable03"
$04 = "Cable04"
$05 = "Cable05"

Global $my1array[5] = ["Set1", "Set2", "Set3", "Set4", "Set5"]
Global $my2array[5] = ["Mod1", "Mod2", "Mod3", "Mod4", "Mod5"]
Global $OutputArray[5] = ["#", "#", "#", "#", "#"]

For $i = 0 To UBound($my1array) - 1
   For $j = 0 To UBound($my2array) - 1
        If $my1array[$i] = "Set" & ($i + 1) And $my2array[$i] = "Mod" & ($j + 1) Then $OutputArray[$i] = Eval("0" & $j)
   Next
Next

To be honest though, although I can’t say what you are trying to do, I think you are trying to do it the wrong way.

Your data structures are suspect at least. Have you described what you are trying to do in an earlier post?

If not, it would certainly help

rudi · December 8, 2020

Hello,

as @JockoDundee stated also I cannot guess what your goal is, at all.

But what you are sketching looks to me as a "2D" array task. 2D arrays are still very comfortable to work with, as e.g. _DebugArrayDisplay() works perfectly to take a look at their content.

It's also very easy to add array content using the function _ArrayAdd(). _ArrayAdd() has the very nice effect, that you do not need to know and to take care of the final array dimensions (final number of rows) in advance.

#include <Array.au3>
#include <Debug.au3>


dim $Arr2D[1][3]=[["Cable","Mod","Set"]]

_DebugArrayDisplay($Arr2D)

$Str2Split=""

$Counter=1
for $Set = 1 to 10
    for $Mod = 1 to 10
        $Str2Split&="Cable" & StringFormat("%02i",$Counter) & "|Mod" & StringFormat("%02i",$Mod) & "|Set" & StringFormat("%02i",$Set) & @CRLF
        $Counter+=1
    Next
Next

$Str2Split=StringTrimRight($Str2Split,2) ; cut off last @CRLF

_ArrayAdd($Arr2D,$Str2Split)
_DebugArrayDisplay($Arr2D)

<edit>

somewhat larger array:

#include <Array.au3>
#include <Debug.au3>


dim $Arr2D[1][5]=[["Cable","Mod","Set","Length","Plug"]]

_DebugArrayDisplay($Arr2D)

$StrPlugTypes="CEE16|CEE32|CEE64"
$aPlugs=StringSplit($StrPlugTypes,"|",2)

Dim $Str2Split=""

$Counter=1
for $Set = 1 to 10
    for $Mod = 1 to 10
        for $Lenth = 1 to 10
            for $plug in $aPlugs
                $Str2Split&="Type-" & StringFormat("%03i",$Counter) & "|" & "Mod" & StringFormat("%02i",$Mod) & "|Set" & StringFormat("%02i",$Set) & "|" & StringFormat("%02i",$Lenth) & " ft|" & $plug & @CRLF
                $Counter+=1
            Next
        Next
    Next
Next

$Str2Split=StringTrimRight($Str2Split,2) ; cut off last @CRLF

_ArrayAdd($Arr2D,$Str2Split)
_DebugArrayDisplay($Arr2D)

</edit>

hi,

Have you described what you are trying to do in an earlier post?

i will make a miniture working model so you can understand what i want to do and why i doubt that i can use 2D arrays. might take a while but i will post simplified version within a few hours (i hope) then you can see that only 1D arrays will work even though the task i want to do, would normally be predestined for a 2D array. give me a chance to show you what i am up to, thanks.

hi,

fully functioning working version (very very simplyfied)

now, just try to imagine 100 entries instead of 8. until every possible solution would have been worked through, it would take at least 10000 if cases to ensure that everything is right. ... now take into consideration that maybe it is not linear (like in this small example) but randomized, then you would have 100x100x100 cases which would lead to 1 million if cases

here is the example:

now i do not want to compare two different lines from two different arrays. it must remain linear 1=1=1 ; 2=2=2 ; 3=3=3 ; etc.

i know some will ask: why bother converting the alpabetical entry to a numeric entry? this is an example and in the finished thing there will be something like "Settings" or "Modes" and "Cables" ... Imagine an Errorcode on a computer, it is more or less like that with the difference you know exactly where to look for the error because you get two codes (Settings and Modes) that will then tell you which cable is the one that is producing the error.

that is why my initial question is: is there some way to not write 10000 or even 1000000 lines of code but somehow simplify this procedure?

kind regards to all

i will make a miniture working model so you can understand what i want to do and why i doubt that i can use 2D arrays.

roselapi, 2D arrays may or may not be necessary, but there is little doubt that you are the master of the 0D array

roeselpi,

As the substitution algorithm for the value to insert into $workarray03 based on the values in $workarray01/02 is extremely simple you can shorten the code quite a lot - just look for my comments in the <<<<<<<<<<< lines:

I have no idea what you are doing with this script, but my version gives you the same result as your rather less elegant code - and in my opinion is scalable to deal with a very much bigger $maxsize value without changing a line.

And if $maxsize is very large, you can get rid of $workarray04 and just directly replace the numeric values in $workarray03 with the letters - that would save a fair bit of memory.

Please ask if you have any questions.

@Melba23, great work, but @roeselpi, again what problem are you trying to solve??

And I don’t mean from a programming point of view, but only in the general sense.

I have no doubt that if you share that with this group your ultimate code needed will be vastly reduced, even from the code that’s been posted so far.

roeselpi · December 9, 2020

@Melba23: fantastic. i wish that i could come up with these kind of elegant solutions. with me it never turns out that nice, but hey i at least got the job done with my code as well. it will take a few days to implement and rewrite everything accordingly. thanks a lot for the help so far, that has been really great.

Melba23 · December 9, 2020

roeselpi,

Delighted I could help. But I would echo the comments above - if you could explain just what it is you are trying to do in the "real world" rather than just posting a programming conundrum, we might be able to offer even more elegant solutions.

A good example is a thread from some time ago where in this post the OP explained exactly what he was trying to do:

In this case once we understood the exact requirement we were able to come up with some really good solutions far removed from the original code framework.

last time i did that here, ( see: my (still not quite finished) word scrambler ) i got a reply like this:

In that kind of case you should remake a new thread.

Becose you're asking much different things. and people probably wont read this until here.

i got a lot of help from caramen and have more or less completed my programme from back then ... (one issue remains, but i am a lot further then i was back then) ... mmh, maybe i should look into finishing that as well as it is only a minor thing that must be implemented to make it work the way i had envisioned it.

anyway, i was led to believe that there is no point in writing down what you want to do, but rather more to post individual problems and get solutions for those things, rather than making one thread with all related problems. so i try to stick to that.

half the time i have an idea of what i want to do but encounter something else that would make it better and then just try to do exactly that.

at the end of the day it all boils down to cryptology (cypher-software) based on the shifting of alphabetic and numeric characters with the help of a one-time-pad. only difference in my design is: you will need not just one one-time-pad but rather more two and therefor you would have to encrypt the one-time-pad(s) to decrypt the data. ... in one direction it works beautifully but i have hit a rather big problem within the reverse engineering: something my eye can do which software can not do: since i do not want to end up with encrypted data looking like this "§3eert&vb[;as" but rather more like encrypted data looking like "abcdefg" i have devised a hypothesis that 3 different digits are displayed by one alphabetic symbol. .... in the direction of encryption it is all easy, but in the other direction i have hit a task that seems impossible: i know the values (in numerals or in characters) of the two combined one-time-pad(s) so i have an undisputable fixed set of values that are always there. then on the other hand i have the encrypted data consisting of only alphabetical digits. now i know that an "A" could be one of three different signs, and even if i decode all three versions i will get three differnt outputs and my eye can see a way to get the message out of that, but a software would not be able to determine which letter from which decription would be the right one because it can not determine that two of the three possible decryptions is wrong.

i have been thinking a lot about my problem and at first i thought, well it is no problem if i double the number of letters (characters) because i have numeric values as well. but that would make a longer message than i would hope for. "hello world" would not be "acfgh mnopq" but rather more "aaccffgghh mmnnooppqq" and that is no good at all. a bit of a bummer, so it looks like a dead end for the time being.

i will look further into the encryption for now and get the system running to the way i envision it, then it all comes down to the reverse engineering and that will probably ultimatly be the end of the line because there will be no way to accomplish that without flaw. but i will press on until i reach that point.

i might have another question here or there but probably deal with that in a different thread.

kind regards
