Answer 1

What you can do is write the answer to a (temporary) file and compare the files. For example:

...
echo %choice% > tempfile.txt
fc tempfile.txt test.txt > NUL
if errorlevel 1 echo answer is different as text.txt

Answer 2

Will ask to enter a password guess and will output to a results.txt if found.

@echo off
echo Password comparer
set choice=
set /p choice=Enter your password guess:

TYPE test.txt | findstr /m %choice% > results.txt
