The != operator is

synthesized

from operator==.

I satisfies /*different-from*/<basic_const_iterator> if std::same_as<I,basic_const_iterator<Iter>> is false.

Parameters

s - a sentinel for Itery - a value to compare with Return value

1)base()==s

2)base()<y.base()

3)base()>y.base()

4)base()<=y.base()

5)base()>=y.base()

6)base()<=>y.base()

7)base()<y

8)base()>y

9)base()<=y

10)base()>=y

11)base()<=>y

Notes

Overload (

) can be used to compare two basic_const_iterator<Iter> values if Iter models sentinel_for<Iter>.
