documentclass{minimal}

usepackage{ulem}



book = 1

phone = 0

photocopy = 1

internet = 0

tablet = 1



begin{document}

Book, xout{phone}, photocopy, xout{internet}, tablet, ldots free or open.

end{document}

I would like to mention which materials students can use for the exam. If the material is 1, write the name of the material. I want it to write as xout if the material is 0. I've added a picture below.

You could use something like this:

documentclass{article}

usepackage{ulem}



newcommand{book}{1}

newcommand{phone}{0}

newcommand{photocopy}{1}

newcommand{internet}{0}

newcommand{tablet}{1}



newcommand{allowed}[2]{%

    ifnum#1=1

        #2%

    else%

        xout{#2}%

    fi%

}



begin{document}



allowed{book}{books}, allowed{phone}{phone}, allowed{photocopy}{photocopies}, allowed{internet}{internet}, allowed{tablet}{tablet}, ldots free or open.

end{document}

Personally I would not use such a notation for an exam but be on the safe site and explicitly write

• allowed items: ....




• forbidden items: ....

to avoid potential misunderstandings and legal problems.
