# operator==(ranges::join_view::iterator, ranges::join_view::sentinel)

From cppreference.com
< cpp‎ | ranges‎ | join view‎ | sentinel

friend constexpr bool operator==( const /*iterator*/<Const>& x, const /*sentinel*/& y ); |  | (since C++20)

Compares the underlying iterator of `x` with the underlying sentinel of `y`.

This function is not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when `join_view::sentinel<Const>` is an associated class of the arguments.

The `!=` operator is synthesized from `operator==`.

### Parameters

x | - | iterator to compare
y | - | sentinel to compare

### Return value

x.current_ == y.end_, where `current_` denotes the underlying iterator, `end_` denotes the underlying sentinel.
