Can You Create a `std::vector` in C 11?

Is Vector Permissible in C 11?

C standards have undergone revisions over time, notably from C 03 to C 11, leading to stricter requirements for each container operation. This allows for the inclusion of types that are copy-constructible but not assignable, such as structures with const members, in vectors as long as specific operations are performed (e.g., construction and push_back).

The inquiry arises as to whether this relaxation in standards allows for the creation of vector in C 11. However, this is not the case. The allocator requirements mandate that T be a "non-const, non-reference object type."

The inability to do much with a vector of constant objects, as well as the near equivalence of a const vector, further disincentivizes the creation of vector.

The C standards over the years have continuously refined this aspect, from explicitly barring any type in C 03 to excluding even const and volatile object types in C 17.
