NAME¶

std::counted_iterator::operator= - std::counted_iterator::operator=

Synopsis¶

template< class I2 >

requires std::assignable_from<I&, const I2&> (since C++20)

constexpr counted_iterator& operator=( const counted_iterator<I2>&
other );

The underlying iterator and length are assigned with those of other.

Parameters¶

other - iterator adaptor to assign from

Return value¶

*this

Example¶

// Run this code

#include <algorithm>
#include <cassert>
#include <initializer_list>
#include <iterator>

int main()
{
auto a = {3, 1, 4, 1, 5, 9, 2};
std::counted_iterator<std::initializer_list<int>::iterator> p(begin(a), size(a) - 2);
std::counted_iterator<std::initializer_list<int>::iterator> q;
assert(q.count() == 0);
assert(q.count() != p.count());
q = p;
assert(q.count() == p.count());
assert(std::ranges::equal(p, std::default_sentinel, q, std::default_sentinel));
}
