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

Erases all elements that compare equal to value from the container. Equivalent to c.erase(std::remove(c.begin(), c.end(), value), c.end());

Parameters

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

Complexity

Linear.

Example

Run this code

#include <experimental/vector>
#include <iostream>
 
auto show = [](const auto& container) {
    for (auto e : container) {
        std::cout << e;
    }
    std::cout << '\n';
};
 
int main()
{
    std::vector<int> data{1,1,1,4,1,1,1,2,1,1,1};
    show(data);
    std::experimental::erase(data, 1);
    show(data);
}

Output:
