# std::experimental::erase (std::list)

From cppreference.com
< cpp‎ | experimental

Defined in header `<experimental/list>` |  |
template< class T, class A, class U > void erase( std::list<T, A>& c, const U& value ); |  | (library fundamentals TS v2)

Erases all elements that compare equal to value from the container. Equivalent to c.remove_if([&](auto& elem) { return elem == value; });.

### Parameters

c | - | container from which to erase
value | - | value to be removed

### Complexity

Linear.

### Example

Run this code

    #include <experimental/list>
    #include <iostream>

    auto show = [](const auto& container)
    {
        for (auto e : container)
            std::cout << e;
        std::cout << '\n';
    };

    int main()
    {
        std::list<int> data{1, 1, 1, 4, 1, 1, 1, 2, 1, 1, 1};
        show(data);
        std::experimental::erase(data, 1);
        show(data);
    }

Output:

    11141112111
    42

### Notes

Unlike std::list::remove, this function template accepts heterogeneous types and does not force a conversion to the container's value type before invoking the == operator.
