How can I create two boxes in the same line

Question

How can I create two boxes in the same line with words in between(as the picture below which I made using MS-Word)? I tried \makebox, \fbox or \minipage and none of them seem to be working, maybe because I am using verbatim environment at the same time. I am trying to make a section illustrating how to type Chinese in LaTeX.

I have tried

\fbox{
\begin{minipage}{5cm}
\begin{verbatim}
\documentclass{article}
\usepackage[UTF8]{ctex}
\end{verbatim}  
\end{minipage}
}

or any other possible combination of this three command but the typeset engine always give me errors says there is one extra { at the end of the code, even though it should be the right bracket of \fbox.

Answer 1

For an easy-to-use application, just set these in a tabular:

\documentclass{article}

\begin{document}

Either
\begin{tabular}{ | @{\,} l @{\,} | }
  \hline
  \verb|\documentclass{article}| \\
  \verb|\usepackage[UTF8]{ctex}| \\
  \hline
\end{tabular}
or
\begin{tabular}{ | @{\,} l @{\,} | }
  \hline
  \verb|\documentclass[UTF8]{ctexart}| \\
  \verb|\begin{document}| \\
  \verb|\end{document}| \\
  \hline
\end{tabular}.

\end{document}

Another option using fancyvrb to save the verbatim content and use it inside \fbox:

\documentclass{article}

\usepackage{fancyvrb}

\begin{document}

\begin{SaveVerbatim}{optA}
\documentclass{article}
\usepackage[UTF8]{ctex}
\end{SaveVerbatim}
\begin{SaveVerbatim}{optB}
\documentclass[UTF8]{ctexart}
\begin{document}
\end{document}
\end{SaveVerbatim}

Either \fbox{\strut\BUseVerbatim{optA}} or \fbox{\strut\BUseVerbatim{optB}}.

\end{document}

\struts ensure a consistent baseline with respect to the two verbatims.

With a tcblisting from tcolorbox:

\documentclass[11pt,a4paper]{article}

\usepackage[most]{tcolorbox}

\usepackage{lipsum}

\newtcblisting{mybox}[2][]{%
    nobeforeafter, listing only,
    box align=center,
    sharp corners, width=#2, notitle, size=fbox, #1}

\begin{document}

Either 
\begin{mybox}[after=\ ]{5cm}
\documentclass{article}
\usepackage[UTF8]{ctex}
\end{mybox} 
or 
\begin{mybox}[colback=white]{6cm}
\documentclass[UTF8]{ctexart}
\begin{document}
\end{document}
\end{mybox}
\end{document}

You can use fancyvrb facilities. Note that the environment's contents should be typed at the left margin, due to the properties of verbatim.

Disadvantage: you have to adjust the spacing following the environment.

Advantage: you don't have to guess the width.

\documentclass{article}

\usepackage{fancyvrb}

\newenvironment{FBVerbatim}
  {\VerbatimEnvironment
   \begin{lrbox}{\FBVerbatimbox}
   \begin{BVerbatim}}
  {\end{BVerbatim}
   \end{lrbox}
   \fbox{\begin{tabular}{@{}c@{}}\usebox{\FBVerbatimbox}\end{tabular}}}

\newsavebox{\FBVerbatimbox}

\begin{document}

Either
\begin{FBVerbatim}
\documentclass{article}
\usepackage[UTF8]{ctex}
\end{FBVerbatim}
\ or
\begin{FBVerbatim}
\documentclass[UTF8]{ctexart}
\begin{document}
\end{document}
\end{FBVerbatim}
\,.

\end{document}

Interestingly, \hbox worked (but not \savebox).

\documentclass{article}

\begin{document}
\setbox0=\hbox{\begin{minipage}{5cm}
\begin{verbatim}
\documentclass{article}
\usepackage[UTF8]{ctex}
\end{verbatim}  
\end{minipage}}%
\fbox{\usebox0}

\end{document}
