UML Diagrams

Hi everyone,

is there a tool to generate UML Diagrams from a given code?

google? try "uml generator c++" or better "reverse engineering c++"
list of UML tools, and wikipedia

if you are using Visual Studio, you can install MS Visio. Within VS: Project > Visio UML > Reverse Engineering

I use Umbrello: http://uml.sourceforge.net/
Using Debian it's one apt-get away from you :p

How about doxygen?

According to the Doxygen wiki page, Doxygen can use GraphViz to generate diagrams including class hierarchies and collaboration for C++, Java and Python.
