Can C  11 Vectors Store `const T` Objects?

Can C 11 Use vector?

In C 03, containers had blanket requirements for operations like copy constructibility and assignability. However, C 11 introduced fine-grained requirements for each operation, allowing certain operations on types that are copy-constructible but not assignable.

While this may suggest the possibility of storing const T in a vector, the standard's allocator requirements prohibit this. They specify that T must be a "non-const, non-reference object type."

Storing a vector of constant objects would be impractical, and a const vector would essentially serve the same purpose, rendering vector unnecessary.

Additionally, implementing vector would pose challenges as it would restrict operations and could potentially interfere with exception handling.
