Counting in Multidimensional Arrays

3 posts in this topic

#1 ·  Posted (edited)

I'm working on a script at the moment for practice but i think I've taken a wrong turn,

the intended result is to keep adding names to this array and if two or more names match it'll just increase a count next to their name.

Heres what i have so far:

Global $Names[3] =  ["Harry Potter","Harry Potter","Hermione Granger"]
Global $NameCount[1][2] ; [Index][Name, Count]
$NameCount[0][0] = 0
 
For $a = 0 to UBound($Names)-1 step 1
$Input = $Names[$a]
 
$iSize = UBound($NameCount, 1)
ReDim $NameCount[$iSize + 1][2]
$NameCount[0][0] = $iSize
$NameCount[$iSize][0] = $Input
 
for $i = 1 to $NameCount[0][0]
if $Input = $NameCount[$i][0] Then
$NameCount[$i][1] += 1
;ReDim $NameCount[$iSize+1][2]
EndIf
Next
 
For $i = 1 to $NameCount[0][0]
ConsoleWrite($NameCount[$i][0] & ": " & $NameCount[$i][1] & @CRLF)
Next
ConsoleWrite(@CRLF)
next

Expected Output:

 

Harry Potter: 2

Hermione Granger: 1

 

Current Output:

Harry Potter: 2
Harry Potter: 1
Hermione Granger: 1

you were adding it to the array before checking if is there, sorry I like to write in my manner :)

#include <Array.au3>
Global $Names[3] = ["Harry Potter", "Harry Potter", "Hermione Granger"], $found=0
Global $NameCount[1][2] = [[0,0]] ; [Index][Name, Count]

For $a = 0 To UBound($Names) - 1
    $Input = $Names[$a]

    If $a = 0 Then
        ReDim $NameCount[2][2]
        $NameCount[1][0]=$Input
        $NameCount[1][1]=1
    Else
        ;searching for the name
        For $x = 1 To UBound($NameCount)-1
            If $NameCount[$x][0] = $Input Then
                $found=$x
                ExitLoop
            EndIf
        Next
        If $found Then
            $NameCount[$found][1]+=1
        Else
            ReDim $NameCount[UBound($NameCount)+1][2]
            $NameCount[UBound($NameCount)-1][0]=$Input
            $NameCount[UBound($NameCount)-1][1]=1
        EndIf
        $found=0
    EndIf       
Next
_ArrayDisplay($NameCount)
Exit 

You're using $NameCount[0][0] and $NameCount[0][1] for?

Heroes, there is no such thing

One day I'll discover what IE.au3 has of special for so many users using it.
C'mon there's InetRead and WinHTTP, way better

Its pretty much a score for another project of mine, every time their name is listed add a point, so I'm just making it a tree for how many people are there for the first [0], and the second is their name and how many times they've been listed.

Also this is my first time working with multidimensional arrays so i just wanted to get some practice using them even if there was another way.

Thank you for all your help, i really appreciate it! :)

Edit: NM just got what you meant, bad programming i guess. thanks for pointing that out.

      So I have a loop that keeps reading data from an array and searching it for the same value. If the value is no there it does work then adds the value to the array to prevent it from doing the same work.
      If _ArraySearch($ID,$filearray[$i]) = -1 Then Work.... _ArrayAdd($ID,$filearray[$i]) EndIf This is in a for loop hence $i
      So what is happening is the code works great for several hours. After a period of time _ArraySearch($ID,$filearray[$i]) will result in -1 even if $ID = $filearray. So it ready as if there is no data in the array. Anyone have this problem? 
       
      Also I am just running in using F5 not compiling it and running it if that makes a difference.

      I am reading a CSV file which is tab seperated as below.
      Local $aArray = FileReadToArray($file) And now, I am splitting this main array record wise so that Array contains internally another arrow to represent each row.
      For $i = 0 to (UBound($aArray) - 1) ;MsgBox(0,"",$aArray[$i]) $aArray[$i] = StringSplit(StringStripCR($aArray[$i]), Chr(9),2);Chr(9) for tab ;_ArrayDisplay($aArray[$i]) Next Afther that, _ArrayDIsplay is able to see the individual internal arrays.
      _ArrayDisplay($aArray[1]) But If I try to access the individual element of it as below.It is not showing any result.
      MsgBox(0,"",$aArray[1][1]) Any suggestion, below is the sample csv file.

      Need some help understanding why the ConsoleWrite works inside 2nd For loop but not out side. Between Audit Wiki, Help file , Forum searching (lots of code reading), and YouTube ( shout out to TutsTeach), I have not been able to find the reason why. 
      $sIniPath = "installLog.ini" ; - Get section name $iniSctionNames = IniReadSectionNames($sIniPath) ; - Get Keys and Vaules For $a = 1 to UBound($iniSctionNames) - 1 $keys = IniReadSection($sIniPath , $iniSctionNames[$a]) For $b = 1 to UBound($keys) - 1 $oldSysInfo = IniRead($sIniPath , $iniSctionNames[1], $keys[$b][0], "") $PntIPInfo = IniRead($sIniPath , $iniSctionNames[2], $keys[$b][0], "") $NewPCInfor = IniRead($sIniPath , $iniSctionNames[3], $keys[$b][0], "") ;ConsoleWrite($oldSysInfo & @LF) Next ;ConsoleWrite($oldSysInfo & @LF) Next ConsoleWrite($oldSysInfo) My intention is to use the variables later for Listboxes. Any explanation, forum post links or whatever would help. Sorry also very very new to Autoit.
      Also here's the ini file.
