Packages to load after automultiplchoice

You must load the following packages after automultiplechoice : fancyvrb, fancybox, pstricks.

To use PSTricks, you have to configure AMC : Edit → Preferences → Main → Default LaTex engine → latex+dvipdf

verbatim

From wiki.

The verbatim environment interferes with AMC LaTeX package, so that it is impossible to use it inside question or questionmult environments... As an example, the following code won't compile:

\begin{question}{program}
What is the return value of the following R code?
\begin{verbatim}
sum(sapply(1:2^2,function(x) { x/2 }))
\end{verbatim}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}

Escaping

For very small texts, it is possible to escape all characters that have a special meaning for LaTeX. However, this can become quickly tedious.

\begin{question}{program}
What is the return value of the following R code?
\begin{center}
\texttt{sum(sapply(1:2\textasciicircum 2,function(x) \{ x/2 \}))}
\end{center}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}

\UseVerb from fancyvrb package.

https://www.ctan.org/pkg/verbatim.

You can also record some one-line verbatims with the fancyvrb package (define your verbatim outside, before \onecopy):

\SaveVerb{theRcode}'sum(sapply(1:2^2,function(x) { x/2 }))'
...
\begin{question}{program}
What is the return value of the following R code?
\begin{center}
\UseVerb{theRcode}
\end{center}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}

verbatimbox package

For larger verbatims, the verbatimbox package can help you (define your verbatim outside, before \onecopy):

\begin{myverbbox}{\Rcode}
sum(sapply(1:2^2,function(x) { x/2 }))
\end{myverbbox}
...

\begin{question}{program}
What is the return value of the following R code?
\begin{center}
\Rcode
\end{center}
\begin{choices}[o]
\wrongchoice{2.5}
\correctchoice{5}
\wrongchoice{NaN}
\end{choices}
\end{question}

Import external files

Reading the verbatim from a separate file often helps. As an example, for a syntax highlighted python code stored in a file named prog.py in the project directory, you can use

listings package

\lstset{language=Python}
\lstinputlisting{prog.py}

minted package

 \inputminted{python}{prog.py}
