tlug: Books on C++, graph of functions

[Ulrike Schmidt <798a5047@example.com>]

I have two unrelated questions:

(1) I have to learn C++. Which books or online tutorials woudl you recommend?
(2) I have to find my way through some confusing perl-Modules and thought
of writing a script that finds out which function calls which and to feed a
graph drawing program. Since the Perl interperter probably also collects
this information at some stage I was wondering whether there is a simple
way to get to this information. Or maybe emacs can do this as well? Or
maybe there already are some tools that draw graphs from functions etc. ?
