    It doesn't work because -name expects a shell pattern. You can use -regex instead, or just assemble your pattern like so:

    find . -name '*.c' -o -name '*.h' -o -name '*.cc'

    Edit
    To do this with a single pattern you'll want a regex:

    find . -regextype posix-extended -regex '.*\.(c|h|cc)'

    You could do it with the default emacs regexes, I'm sure; I don't use them or know the main differences so I picked the one I know.

    If you really want to use a single shellglob, you're out of luck: the only syntax for multiple strings is {a,b}, and this is not supported by find. But there's nothing wrong with the sort of command building/chaining in my first example. It's how find is intended to be used.

  2. If you really want to use a regex then 

     find -regex "\(.*\.[hc]\|.*\.cc\)"

    should do the trick but the more normal way to do this is to use -o as already demonstrated.
