自增或自减迭代器。

1,2) 分别前自增或前自减一。

3,4) 分别后自增或后自减一。

5,6) 分别返回前进 n 或 -n 个位置的迭代器。

7,8) 分别令迭代器前进 n 或 -n 个位置。

参数

n

-

相对于当前位置的位置

返回值

1,2) *this

3,4) *this 修改前的副本，然而若 Iter 不实现 forward_iterator，则后自增运算符不返回这种副本而返回类型为 void (C++20 起)。

5,6) 分别为 move_iterator(base()+n) 或 move_iterator(base()-n)。

7,8) *this
