Comparing variables

[AutID]

Hello,

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"

$c = "Y"

 

Is there a way to compare $c with these variables and find which one is the right one without having to use an if/elseif/endif statement???

I tried a stringinstr but not much success.

AutId,

Here is one way:

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"

$c = "Y"

for $1 = 1 to 5
    if eval($1) = $c then consolewrite('$' & $1  & ' is equal' & @lf)
next

However, if you are interested in storing values for later lookup there are much better techniques than individual variables.  If you explain a little about what you are doing you will receive a better answer.

AutID,

Your script doesn't show, than "if/elseif/endif" is bad

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"

$c = "Y"
If $1 = "Q" And $2 = "W" And $3 = "Y" And $4 = "U" And $5 = "S" Then MsgBox(0, ';)', 'Yes')

kylomas,

What if $c is "Q"?

AZJIO,

AutID wants to compare $c to $1 to $5. What is your example doing, exactly?

AutID,

It would be easier to use an array:

#Include <Array.au3>

Local $Values[5] = ["Q", "W", "Y", "U", "S"]
Local $c = "Y"

Local $Index = _ArraySearch($Values, $c)

If $index >= 0 Then
    ConsoleWrite("$c was found in $Values at index " & $index & @LF)
Else
  ConsoleWrite("$c was not found in $Values" & @LF)
EndIf

You can also use Select...Case...EndSelect.

@jchd - Ha! How stupid, I overwrite the value of $1...thanks.

This stands however.  You used an array but it could also be a string.

OP has explicitly requested "without having to use an if / elseif / endif statement"

maybe he meant something like this (no command IF it's required)

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"

$c = "Y"

dim $oracle[2] = ["not equal","equal"]

for $1 = 1 to 5
    ConsoleWrite("$" & $1 & " " & $oracle[(eval($1) == $c)] & " $c" & @crlf)
next

bye

@PincoPanco, you have a bug in your script. This will prevent your script from comparing $c to $1 so if $c = "Q", the script displays all as "not equal".

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"

$c = "Y"

dim $oracle[2] = ["not equal","equal"]

for $1 = 1 to 5 ; <<<<<<<<<<<<<<<<<<<<< you're reusing the variable $1
    ConsoleWrite("$" & $1 & " " & $oracle[(eval($1) == $c)] & " $c" & @crlf)
next

[Gianni]

ops
BrewManNH you're right
I modified kylomas's example from post >#2 without changing the loop variable
using a different loop variable name works well

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "Y"

$c = "Q"

dim $oracle[2] = ["not equal","equal"]

for $X = 1 to 5
    ConsoleWrite("$" & $X & " " & $oracle[(eval($X) == $c)] & " $c" & @crlf)
next

kylomas,

What if $c is "Q"?

AZJIO,

AutID wants to compare $c to $1 to $5. What is your example doing, exactly?

AutID,

It would be easier to use an array:

#Include <Array.au3>

Local $Values[5] = ["Q", "W", "Y", "U", "S"]
Local $c = "Y"

Local $Index = _ArraySearch($Values, $c)

If $index >= 0 Then
    ConsoleWrite("$c was found in $Values at index " & $index & @LF)
Else
  ConsoleWrite("$c was not found in $Values" & @LF)
EndIf

You can also use Select...Case...EndSelect.

Tu es le seul qui a compris

I came up with this after jchd's sample.

#Include <Array.au3>
$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"
Local $Values[5] = [$1, $2, $3, $4, $5]
Local $c = "Y"
Local $Index = _ArraySearch($Values, $c)
ConsoleWrite($Values[$index] & @LF)

[BrewManNH]

I thought you wanted to avoid using If/ElseIf/Else? _ArraySearch is loaded with them.

[AutID]

I thought you wanted to avoid using If/ElseIf/Else? _ArraySearch is loaded with them.

They are not in my script though

[BrewManNH]

Actually, yes they are, they aren't in what you wrote, but they're definitely in your script.

[AutID]

Actually, yes they are, they aren't in what you wrote, but they're definitely in your script.

You know what I mean...

[Gianni]

I agree with BrewManNH That _ArraySearch is full of "IF"
(you do not see them only because they hid behind #Include <Array.au3>
and what will happens to your code if "Y" are more than 1, or even worse, none?

well, allowing the use of #include <Array.au3>, can you manage that cases? (without the "IF" statement ofcourse)
if you need a tip as well ask

[Edano]

wow, is this still hot or a competition ???

.

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"

$c = "Y"

$string=$1&$2&$3&$4&$5

MsgBox(0,"",StringInStr($string,$c))

.

E.

Edit: of course, using includes is cheating. you could include every au3 script you want, even self written. this is cheating

and if you want casesense and occurence, take this:

.

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"
$6 = "Y"

$c = "Y"

$i=0
$string=$1&$2&$3&$4&$5&$6

Do
    $i+=1
    $ret=StringInStr($string,$c,1,$i)
    MsgBox(0,"",$ret)
Until $ret=0

MsgBox(0,"",StringTrimRight("no (more)",7*($i=0))&" '"&$c&"' found.")

.

no "if"

Edit: Bool is not "If"

it finds one more, even if there are not

[Edano]

nonono, zero is defined as failure !

[Gianni]

better without the view of that failure....

[Edano]

$1 = "Q"
$2 = "W"
$3 = "Y"
$4 = "U"
$5 = "S"
$6 = "Y"

$c = "Y"

$i=0
$string=$1&$2&$3&$4&$5&$6

Do
    $i+=1
    $ret=StringInStr($string,$c,1,$i)
    MsgBox(0,"",StringReplace($ret,"0","that's all"))
Until $ret=0

MsgBox(0,"",StringTrimRight("no (more)",7*($i=0))&" '"&$c&"' found.")
