Inserts the given value value to the container.
1) Results in
iter = container->insert(iter, value); ++iter;.
2) Results in
iter = container->insert(iter, std::move(value)); ++iter;.
Parameters
| value | - | the value to insert |
Return value
*this
Notes
This function exploits the signature compatibility between hinted insert for associative containers (such as std::set::insert) and positional insert for sequential containers (such as std::vector::insert).
Example
#include <deque>
#include <iostream>
#include <iterator>
int main()
{
std::deque<int> q;
std::insert_iterator<std::deque<int>> it(q, q.begin());
for (int i = 0; i < 10; ++i)
it = i; // inserts i
for (auto& elem : q)
std::cout << elem << ' ';
std::cout << '\n';
