comparing 2d arrays

[NileshSutar]

Hi guys,

i want to compare two "2D" arrays such that it should return 0 if no element is common and 1 if one or more elements are common.How can i do that.???

Hi,

Nested For.

Think in your head how you would do it and then translate it, quite easy.

Post your code, so we can see what you're talking about

Define both arrays by using Global to make them available for every function.

Assuming both arrays has the same number of elements, something like this should work

Func Compare2D(ByRef $Array1, ByRef $Array2)

    Local $Check = 0

    For $x = 0 To UBound($Array1, 1) -1
        For $y = 0 To UBound($Array1, 2) -1
            $Check += ($Array1[$x][$y] = $Array2[$x][$y])
        Next
    Next

    $Check = $Check > 0

    Return $Check

EndFunc   ;==>Compare2D

(not tested)

bye

edit

added -1 to ubound in listing

First check that the dimensions of the array are the same.

Make "ExitLoop" out of the loop if the going does not match. I don't think that should be checked until the end, if the first cell is not the same.
