iterator erase(iterator first, iterator last); (until C++11) iterator erase(const_iterator first, const_iterator last); (since C++11) Erases the specified elements from the container. 1)Removes the element atpos. 2)Removes the elements in the range[first,last). ...
template<class...Args> iterator emplace(const_iterator pos, Args&&...args); (since C++11) Inserts a new element into the container directly beforepos. The element is constructed throughstd::allocator_traits::construct, which uses placement-new to construct the element in-place at a location ...

All iterators and references remain valid. It is unspecified whether an iterator holding theend()value in this container will refer to this or the other container after the operation. Ifstd::allocator_traits<allocator_type>::propagate_on_container_swap::valueistrue, then the allocators are exchan...
const_iterator cbegin()constnoexcept; (3)(since C++11) Returns an iterator to the first element of thelist. If thelistis empty, the returned iterator will be equal toend(). Parameters (none) Return value Iterator to the first element. ...
Return value trueif the container is empty,falseotherwise. Complexity Constant. Example The following code usesemptyto check if astd::forward_list<int>contains any elements: Run this code #include <forward_list>#include <iostream>intmain(){std::forward_list<int>numbers;std::cout<<std::boolalp...
