[Tex/LaTex] Change font size of the verbatim environment

Question

I want to apply small fonts inside the Verbatim environment e.g.

{\small 
\begin{Verbatim}

1   double x, y;
2   double z, w;
3   main();
4   return 0;

\end{Verbatim}}

Before the command \small and after the closing braket } text has normal size, which is obvious but the font size should be small inside the brakets.

Why is this command not applied to the environment's contents?

Answer 1

You appear to be using fancyvrb, which already has the feature you want:

\documentclass{article}
\usepackage{fancyvrb}
\usepackage{lipsum} % just for the example
\begin{document}

\lipsum*[3]
\begin{Verbatim}[fontsize=\small]
1   double x, y;
2   double z, w;
3   main();
4   return 0;
\end{Verbatim}
\lipsum[3]

\end{document}
