Have you checked the man page for Apple's find, notably the -E flag
(and the resulting reference to re_format(7))?

Anyhow, for your particular need, using regexps is overkill.

find . \( -name '*.h' -o -name '*.cpp' \)

will work, and is easier both to type and to read.
You may skip \( and \) in the above usage, but they are needed if you
follow the search term with -print0 or stuff like that.
