The parent is correct. std::vector is a value type in the sense that everyone else is talking about... All types in C++ are, as their members are not inherently stored on the heap. C++ (and C, and Rust) has types that behave like what other languages call value types, even if there is not any other sort of type. The mention of array in the parent was referring to the dynamic storage of a vector, not std::array.
