:mrdocs:

Remove the elements in the half‐open range `[first .. last)]`.

== Synopsis

Declared in `<bslstl_set.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
xref:bsl/set-0d/iterator.adoc[set<KEY, COMPARATOR, ALLOCATOR>::iterator]
erase(
    xref:bsl/set-0d/const_iterator.adoc[const_iterator] first,
    xref:bsl/set-0d/const_iterator.adoc[const_iterator] last);
----

== Description

Return `last`. This method invalidates only iterators and references to the removed element and previously saved values of the `end()` iterator. The behavior is undefined unless `first` and `last` either refer to elements in this set or are the `end` iterator, and the `first` position is at or before the `last` position in the ordered sequence provided by this container.

== Return Value

`last`

== Parameters
