What? C++ strings have an overhead of 16 bytes+the space left in the backing buffer. That’s really not all that much.

16 bytes is in no way guaranteed by the standard.

Of course–the implementation is free to do whatever it likes. But all reasonable ones will either use a three pointer (or some combination of a base pointer and pointers/integers representation bounds) or include a small buffer for SSO that overlaps with the storage for heap bounds.
