Make code in LaTeX look *nice*

Answer 1

The listings package is quite nice and very flexible (e.g. different sizes for comments and code).

Answer 2

For simple document, I sometimes use verbatim, but listing is nice for big chunk of code.

Answer 3

After some lengthy googling, it turns out that lstlisting is able to format code nicely, but it requires a lot of tweaking.

Wikibooks has a good example for the parameters you can tweak.
