std::forwar...erase_after(3) C++ Standard Libary std::forwar...erase_after(3) NAME std::forward_list::erase_after - std::forward_list::erase_after Synopsis iterator erase_after( const_iterator pos ); (1) (since C++11) iterator erase_after( const_iterator first, const_iterator last ); (2) (since C++11) Removes specified elements from the container. 1) Removes the element following pos. 2) Removes the elements following first until last. Parameters pos - iterator to the element preceding the element to re- move first, last - range of elements to remove Return value 1) Iterator to the element following the erased one, or end() if no such element exists. 2) last Complexity 1) Constant. 2) Linear in distance between first and last. Example // Run this code #include <forward_list> #include <iterator> #include <iostream> int main() { std::forward_list<int> l = { 1, 2, 3, 4, 5, 6, 7, 8, 9 }; // l.erase( l.begin() ); // ERROR: No function erase l.erase_after( l.before_begin() ); // Removes first element for( auto n : l ) std::cout << n << " "; std::cout << '\n'; auto fi = std::next( l.begin() ); auto la = std::next( fi, 3 ); l.erase_after( fi, la ); for( auto n : l ) std::cout << n << " "; std::cout << '\n'; } Output: 2 3 4 5 6 7 8 9 2 3 6 7 8 9 See also clear clears the contents (C++11) (public member function) http://cppreference.com 2022.07.31 std::forwar...erase_after(3)
