Free C++ IDE?

[Alexander the Pretty Good]

Any good free (or open source) C++ IDE's out there? I'm using Microsoft Visual C++ 6.0 but are there any alternatives people recommend?

Last year in Uni I used Dev c++, http://www.bloodshed.net/download.html

I found it a pretty good all round IDE especially since its free.

Code::Blocks (http://codeblocks.org/) is another good open source IDE, personally I like it more than Dev-C++.

I used Dev C++ a little, I feel it is a lot simpler than Microsoft Visual C++ ones
