Help?

I'm in a bit of a predicament.

I'm trying to get a code that will determine if a random integer is even or odd, and depending on what the answer is perform from two different actions each time the script is referred to.

Here's my code:


set /a compnumber=%random%

set /a modulo = “%compnumber% %% 2?
if %modulo% == 0 (
rem echo EVEN
) else (
rem echo ODD
)
pause

set /a compnumber=%random%

set /a modulo="%compnumber% %% 2"
if %modulo% == 0 (
rem echo EVEN
) else (
rem echo ODD
)
pause

Did you even change anything?

Did you even change anything?

I see at least 3 changes to the code.

Code: Select all

set /a compnumber=%random%

set /a "modulo=compnumber %% 2"
if %modulo% == 0 (
rem echo EVEN
) else (
rem echo ODD
)
pause

Another method to determine the parity is to make the number and 1 to do a BITAND operation.

Code: Select all

set /a compnumber=%random%

set /a "modulo = compnumber & 1"
if %modulo% == 0 (
rem echo EVEN
) else (
rem echo ODD
)
pause

Another method:

Code: Select all

@echo off
set num=%1
set num=%num:~-1%
for /f "delims=13579" %%a in ("%num%a") do if "%%a"=="a" (echo odd) else (echo even)
pause

I see one change. Must be my old eyes.

I also see only one change.

Squashman means to remove the 2 spaces?

set /a modulo_=_"%compnumber% %% 2"

Removed the spaces.
Added the correct quotes.
Removed the question mark.

Ahh, I told you it was my eyes.

At least we have more than 2 versions to rely on. But still,

Removed the spaces.
Added the correct quotes.
Removed the question mark.

Thank you very much.
