Program to create a UML diagram for C++

Was wondering what the easiest way to create a UML diagram for a c++ program would be? I saw some threads about a java plugin that would create the UML diagram开发者_运维问答 for you, was wondering if there was one like it for C++ (using cygwin on windows).

If not any good freeware programs? I have visio I was just seeing if there were other alternatives (even used mspaint before :P)

Thanks :)

Pen and paper. Actually a pencil with an eraser might be better than a pen. No, seriously, it'll be much easier than using a program.

For anyone who is looking for something similar I recommend StarUML.

Simply install it, go to the tools tab, c++, reverse engineer and follow the options.

Worked better than expected :)

If its a project then Enterprise Architect can help. And Dox. UML Studio

But, you can just do it manually.
