Common array

[lsakizada]

Hi,

I want to create third array from two unique arrays that not contain the common elements.

For example

Dim $aArray_A[3] = ["A","B","C"]

Dim $aArray_B[1] = ["A"]

The expected results:

Dim $aArray_C[2] = ["B","C"]

Please do not take an account case sensitive or not sensitive

Whats the best way to do it?

Isn't that what _ArrayConcatenate does?

never used it..just speculating ;-)

billo,

_ArrayConcatenate does what it says - it adds the 2 arrays together.

lsakizada,

Copy the larger array to the array you want to end with. Loop through the smaller array. For each element do an _ArraySearch in the copied array and _ArrayDelete any matches. At the end you have an array holding those elements from the larger array which are not in the smaller.

There are a whole flock of useless _Array...() functions, but nothing that suits your need.

I'd think you'd need nested loops to manually compare your arrays and delete matches. Then you could go with an _ArrayConcatenate() and an _ArraySort() if needed. Maybe even throw in an _ArrayUnique() if you're concerned about dupes within a single source array.

I love this forum! 5 minutes and 4 replies !!!!

Thank you all guys, the link from JohnOne contain the code and the comments from Melba23 is a short brief of it.

Regards.

You might play with this...

#include <Array.au3>

Global $avArray1[5] = ["Valik", "Holger", "Jon", "Larry", "Jeremy"]
Global $avArray2[5] = ["Valik", "Cyberslug", "Nutster", "Tylo", "JdeB"]
Global $ylen = UBound($avArray2) - 1

For $x = 0 to UBound($avArray1) - 1
    For $y = 0 to $ylen
        If $avArray1[$x] = $avArray2[$y] Then
            ExitLoop
        EndIf
    Next
    If $y > $ylen Then _ArrayAdd($avArray2, $avArray1[$x])
Next

_ArrayDisplay($avArray2)

Whether you need to sort the result at the end, or perform an _ArrayUnique upon $avArray1 prior to combining them would be determined by your requirements.

Edit: poop. too slow!
