In C/C++ a flexible array is a member of a struct that is an array (not just a pointer) but doesn't specify a length (reference). As such, a struct with a flexible array is an incomplete type, so the typeof operator can't be used.

A dynamic array is an ordered collection (list) that can grow and shrink. Dynamic arrays are usually implemented as a linked list or something similar.

Dynamic arrays have values that can be changed by code and more values populated. The flexible array is an array that does not have a hard coded limit to its length.
