Eclipse Cpp - What is the difference between C Project, C/C++ Project and C++ Project?

In Eclipse CDT IDE that i downloaded for Linux (because unfortunately Code::Blocks on Linux/Unix doesn't work so well for me) i am given these three options for creating a project. I can understand the difference between a C and a C++ Project of course. But what exactly is the C/C++ Project? Which one should i choose for C++ development? I can't find clear information on this. Thanks in advance.
