constexpr auto end() const;	(1)	(C++20 起)
constexpr /*iterator*/ end() const requires std::same_as<W, Bound>;	(2)	(C++20 起)

1) 獲取表示哨兵值的哨兵。

• 如果 Bound 是 std::unreachable_sentinel_t，則返回 std::unreachable_sentinel。
• 否則，返回 sentinel {bound_ }。

2) 獲取指向哨兵值的迭代器。

返回值

1) 如上所述。

2) iterator {bound_ }

示例

執行此程式碼

#include <iostream>
#include <ranges>
 
int main()
{
    auto iota{std::views::iota(2, 6)};
    auto end{iota.end()};
    for (auto iter{iota.begin()}; iter != end; ++iter)
        std::cout << *iter << ' ';
    std::cout << '\n';
}
