Powershell: Combining variables -

i'm new powershell , have question:

i made function:

function a_function($a,$b){     $d = $a + $b     $d } a_function "0","1" 

the problem is, function gives output:

0 1 

and on 1 line:

01 

i tried things like:

$d = ($a + $b) #result: same sabove $d = (""+$a + $b+"") #result: 1 0, dont want space inbetween $d = "$a$b" #result: 1 0, dont want space inbetween 

thank helping

you sending array , bind $a only. in powershell delimit arguments space. try way instead:

a_function "0" "1" 

also note you're adding 2 strings, result "01" ant not 1, in case wanted add numbers.
