It depends on what you mean by good but you might try jGrasp, which supports a variety of languages, including C++, Java, and Objective-C.
I like Xcode too! I know there was a bit of a debate going on in another thread about which IDE to use for Java development, but for C, C++ Xcode is pretty good I think. I'm looking forward to the new editor in Xcode 3 with its code folding feature.
macman2790, I find the 'all-in-one' layout the nicest to work in. Have you given it a go?

Eclipse and CDT?
i can't seem to find any IDE other than xcode. xcode is ok, but it's just not my cup of tea.
