Std istreambuf_iterator
Webstd::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。 默认构造的 std::istream_iterator 被称为 流尾 迭代器。 合法的 std::istream_iterator 抵达底层流尾时， … Webstd::istreambuf_iterator is a single-pass input iterator that reads successive characters from the std:: basic_streambuf object for which it was constructed. The actual read operation …
