If you like Eclipse for Java, I suggest Eclipse CDT.
Despite C/C++ support isn't so powerful as is for Java, it still offers most of the features. It has a nice feature named Managed Project that makes working with C/C++ projects easier if you don't have experience with Makefiles. But you can still use Makefiles.
I do C and Java coding and I'm really happy with CDT. I'm developing the firmware for a embedded device in C and a application in Java that talks to this device, and is really nice to use the same environment for both. I guess it probably makes me more productive.
