class istream_iterator; (C++17 起) std::istream_iterator 是单趟输入迭代器,从为之创建迭代器的 std::basic_istream 对象读取 T 类型的相继对象,通过调用适当的 operator>> 。实际读取操作在自增,而非解引用迭代器时进行。在构造迭代器时读取首个对象。解引用只返回最近读取的对象的副本。

std::istreambuf_iterator是单趟迭代器,从为之构造迭代器的std::basic_streambuf对象读取相继字符。 默认构造的std::istreambuf_iterator迭代器被称为流尾迭代器。合法的std::istreambuf_iterator抵达底层流结尾时,它变得等于流尾迭代器。解引用或进一步自增它导致未定义行为。
