std::back_insert_iterator<Container>::operator= – std::back_insert_iterator<Container>::operator=

Synopsis

back_insert_iterator<Container> &(until C++ 11)

operator=(typename Container::const_reference value);

back_insert_iterator<Container> &(since C++ 11)

operator=(const typename Container::value_type &value);
(until C++ 20)

    constexpr back_insert_iterator<Container> &(1)(since C++ 20)

    operator=(const typename Container::value_type &value);

back_insert_iterator<Container> &(since C++ 11)

operator=(typename Container::value_type &&value);
(2)(until C++ 20)

    constexpr back_insert_iterator<Container> &(since C++ 20)

    operator=(typename Container::value_type &&value);

Inserts the given value value to the container.
1) Results in container->push_back(value)
2) Results in container->push_back(std::move(value))

Parameters

value – the value to insert

Return value

*this

Example

// Run this code

#include <iostream>

#include <iterator>

#include <deque>
int main()

{
    std::deque<int> q;
    std::back_insert_iterator<std::deque<int>> it(q);
    for (int i = 0; i < 10; ++i)
        it = i; // calls q.push_back(i)
    for (auto &elem : q)
        std::cout << elem << ' ';
}

Output:
