How to include a code snippet in a beamer presentation?

开发者_运维问答What's the best way to include some code snippets in a beamer presentation?

I've already tried verbatim, and lstlisting environments - both destroyed my presentation.

Use the [fragile] option:

\begin{frame}[fragile]
\begin{verbatim}
...
\end{verbatim}
\end{frame}

I recently used something like

\verbatiminput{blah.c}

in a beamer presentation, and it worked alright for me...

Wanna post your code?
