cxx: fix some compilation warnings in C++ examples

Summary:
Fix some warnings in the C++ examples for elementary. These examples are build
by default in the normal meson compilation.

Only accidental warnings were fixed, explicit warnings using the `#warning`
preprocessor directive were maintained.

Test Plan: Compile with C++ binding.
