Use an existing C++ parser (you're unlikely to ever succeed in writing one yourself that cover all the corner cases of the grammar, it's horrendous).

I can only recommend the Clang libraries.

Parsing C++ is an immense undertaking, so step 1 is to use an established parser that someone else has already written. boost.wave is a good place to start.
