Everybody knows that removing an element from a vector while iterating is a complex task for almost any language -_-' but just try to do it with c++ and get ready to discover that the most robust language is also the one that sucks shit the most

Iterators aren't really meant for this use case, you want a filter operation or something

"most robust language" - citation needed

Sounds like an accidental O(n^2) in the making.

linked lists make that absolutely trivial?

You should not use a 15 kg hammerhead to make a nail...

An iterator iterates. That's it.

While some languages implement an eg "copy on write" approach to allow modification... It's in my opinion definitely wrong - yes, yadda yadda easy and comfortable, but most approaches (as other people mentioned) will create an copy per modification...

Oops.

There are many alternatives...

Stream -/ Map & Filter
Loop -/ Index & Modify
...

An iterator is a simplified way to allow a generalized, read only access to any data structure - object / array / list, you name it.

i call for @FrodoSwaggins for some input

why the fuck would you do that?

@Root But linked lists are usually a very bad data structure these days because they trash cache locality.
