WebHowever, the remove() function takes a non-const reference to an iterator and so we have a problem. One solution is to change remove to use move semantics. Another problem is easily shown when using this common C++11 idiom … WebAlso, returning auto as iterator type seems just fine in C++17. Make our iterator immutable. By default, Iterator can alter the element it points to. If you want to make it immutable, the common trick is to add another iterator type to the custom container class — let's call it ConstantIterator. check engine light free diagnostic
