I'm a bit new to Eclipse, so this is likely a noob problem: I have a C file open in my project and the only colours I see in the editor (containing 200+ lines of code) are black and white. I've looked in Preferences|C/C++|Editor|Syntax Coloring and this stuff is all enabled, so I don't know what it's waiting for. The outline tab says "An outline is not available". Is that related?
I'm running:
Eclipse IDE for C/C++ Developers

Version: Indigo Service Release 1
Build id: 20110916-0149
What that doesn't seem to tell you is that it's 64-bit (I seem to remember installing) and running Win7.

You may have opened the file in the generic text editor and not the
C/C++ editor.

You can switch the editor used to open a file by right clicking on the
file and selecting Open with... menu. Choose C/C++ editor.

Also make sure that the project is a C/C++ project.

What's the ending of your file? Usually the C editor opens automatically when your file has the ending *.c, *.C, *.cpp, *.c++, , *.cc, *.cxx, *.h, *.hh, *.hpp, *.hxx

See Preferences->C/C++->File Types

Before you ask
- search this forum
- see the FAQ http://wiki.eclipse.org/CDT/User/FAQ

"Open with..." worked. Thanks. Strange it couldn't figure this out on its own. The file name is "main.c".
Also, how do I make sure that the project is C/C++? When I right-click on the project in the "Project Explorer" and select "Properties" I don't find any combo box or anything that let's me select the language, but looking through the many options, I see a lot of project settings that are all ready to expect a C/C++ project to the exclusion of any other language.
