constexpr const charT* c_str() const noexcept;constexpr const charT* data() const noexcept;

Returns: A pointer p such that p + i == addressof(operator[](i)) for eachi in [0, size()].

Complexity: Constant time.

Remarks: The program shall not modify any of the values stored in the character array; otherwise, the behavior is undefined.

constexpr charT* data() noexcept;

Returns: A pointer p such that p + i == addressof(operator[](i)) for eachi in [0, size()].

Complexity: Constant time.

Remarks: The program shall not modify the value stored at p + size()to any value other than charT(); otherwise, the behavior is undefined.

constexpr operator basic_string_view<charT, traits>() const noexcept;

Effects: Equivalent to:return basic_string_view<charT, traits>(data(), size());

constexpr allocator_type get_allocator() const noexcept;

Returns: A copy of theAllocatorobject used to construct the string or, if that allocator has been replaced, a copy of the most recent replacement.
