[Tex/LaTex] Defining new command for Multiple Choice Questions

auto-multiple-choiceexam

I checked out this page and they have very good answers but not exactly what I'd need. I would want the justification to be like it is in the answer they gave with everything in one line touching the margins but would like to make a new command for it instead of typing everything each time. Something like it is given in this page

\choice{apple}{banana}{orange}{pear}

So I tried defining a command like

\documentclass[a4paper,addpoints,answers,12pt]{exam}
\usepackage{graphicx,tabularx,caption,color,subcaption,amsmath,amssymb,lmodern,textcomp,gensymb,ifpdf,ifthen}

\newcommand{\mcq}{%
    \begin{oneparchoices}
        \choice #1
        \choice #2
        \choice #3
        \choice #4
        \choice #5
    \end{oneparchoices}
}
    \begin{document}
        \mcq{uihoo}{eifhw2u}{fiwuhr}{fjwhf}{fnweir}
    \end{document}

But this has too many errors:

line 12: Illegal parameter number in definition of \mcq. }
line 12: Illegal parameter number in definition of \mcq. }
line 12: Illegal parameter number in definition of \mcq. }
line 12: Illegal parameter number in definition of \mcq. }
line 12: Illegal parameter number in definition of \mcq. }
line 14: You can't use `macro parameter character #' in horizontal mode. \mcq
line 14: You can't use `macro parameter character #' in horizontal mode. \mcq
line 14: You can't use `macro parameter character #' in horizontal mode. \mcq
line 14: You can't use `macro parameter character #' in horizontal mode. \mcq
line 14: You can't use `macro parameter character #' in horizontal mode. \mcq

I will try whatever solution given with oneparcheckboxes too but let's first have this answer.

You need to tell LaTeX how many arguments there will be:

\newcommand{\mcq}[5]{...

You could update \CorrectChoice to insert an incremental \label. However, this would mean that only the most recent \CorrectChoice would be returned through a \theCorrectChoice call:

enter image description here

\documentclass{exam}% http://ctan.org/pkg/exam

\newcounter{correctchoicemark}% Counter to keep track of correct choice mark
\newcommand{\theCorrectChoice}{\ref{correctchoice-\thecorrectchoicemark}}% Print correct choice
\renewcommand{\choiceshook}{% Adapt \CorrectChoice to insert \label
  \let\oldCorrectChoice\CorrectChoice% Store \CorrectChoice in \oldCorrectChoice
  \renewcommand{\CorrectChoice}{%
    \oldCorrectChoice% Original \CorrectChoice
    \stepcounter{correctchoicemark}% Increment correct choice mark
    \label{correctchoice-\thecorrectchoicemark}% \label original \CorrectChoice
  }%
}
\let\oldoneparchoices\oneparchoices
\renewcommand{\oneparchoices}{%
  \oldoneparchoices% Original oneparchoices environment start
  \let\oldCorrectChoice\CorrectChoice% Store \CorrectChoice in \oldCorrectChoice
  \renewcommand{\CorrectChoice}{%
    \oldCorrectChoice% Original \CorrectChoice
    \stepcounter{correctchoicemark}% Increment correct choice mark
    \label{correctchoice-\thecorrectchoicemark}% \label original \CorrectChoice
  }%
}
\begin{document}

\begin{questions}

  \question This is a multiple choice question
  \begin{choices}
    \choice this is a choice
    \choice this is another choice
    \CorrectChoice this is the correct choice
    \choice this is another choice
  \end{choices}

  The answer is \theCorrectChoice.

  \question This is a multiple choice question
  \begin{oneparchoices}
    \choice this is a choice
    \CorrectChoice this is another choice
    \choice this is the correct choice
    \choice this is another choice
  \end{oneparchoices}

  The answer is \theCorrectChoice.

\end{questions}

\end{document}

exam provides a hook into the choices environment via \choiceshook. Updating this to redefine \CorrectChoice is one (clean) way of inserting the appropriate code to obtain a \label you can \reference. oneparchoices does not provide this hook, so a different method altogether is employed in order to redefine \CorrectChoice.

More work is required for this solution to work correctly with hyperref.

1) I used xpatch to fix the amount of space after each choice.

2) I renewed the \questionlabel command for the first question. \phantom{} reserves the space of the question number but it is not printed. I reset it it back to the class default before the section question.

\documentclass[addpoints]{exam}
\usepackage{xpatch}

% Need both to patch both instances (choice, correctchoice) in the oneparchoices environment.
% Unless there is a global replacement that works within an environment. I don't know.
% Replaces \hskip 1em with \hfill
\xpatchcmd{\oneparchoices}{\penalty -50\hskip 1em plus 1em\relax}{\hfill}{}{}
\xpatchcmd{\oneparchoices}{\penalty -50\hskip 1em plus 1em\relax}{\hfill}{}{}

\begin{document}
\begin{center}
\gradetable
\end{center}
\begin{questions}

\renewcommand\questionlabel{\phantom{\thequestion.}}
\titledquestion{\textbf{Multiple Choice}}[10]
What is the Capital of the United States in 1799?

\begin{oneparchoices}
\choice NY
\CorrectChoice Washington D.C.
\choice Chicago
\choice LA
\end{oneparchoices}

\renewcommand\questionlabel{\thequestion.}
%\setcounter{question}{0}   %Uncomment if you want the first numbered question to start at 1.

\question[10]
What is the Capital of the United Kinddom in 1999?

\begin{oneparchoices}
\choice London 
\CorrectChoice Washington D.C.
\choice Chicago
\choice Los Angeles
\end{oneparchoices}

\end{questions}
\end{document}
