std::list::erase

From Cppreference


iterator erase( iterator position ); iterator erase( const_iterator position );	(1)	(pre-C++11 version) (C++11 version)

iterator erase( iterator first, iterator last ); iterator erase( const_iterator first, const_iterator last );	(2)	(pre-C++11 version) (C++11 version)

Removes specified elements from the container.

1) Removes the element at pos.

2) Removes the elements in the range [first; last).

#include <list>
#include <iostream>
 
int main( )
{
    std::list c{0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
    for (auto &i : c) {
        std::cout << i << " ";
    }
    std::cout << '\n';
 
    c.erase(c.begin);
 
    for (auto &i : c) {
        std::cout << i << " ";
    }
    std::cout << '\n';
 
    c.erase(c.begin + 2, c.begin + 5);
    for (auto &i : c) {
        std::cout << i << " ";
    }
    std::cout << '\n';
}

Output:

0 1 2 3 4 5 6 7 8 9
1 2 3 4 5 6 7 8 9
1 2 6 7 8 9

[edit] Complexity

1) Constant.

2) linear in the distance between first and last.
