Time complexity is constant.ExampleThe following example shows the usage of std::set::erase.Open Compiler #include <iostream> #include <set> int main () { std::set<int> myset; std::set<int>::iterator it; for (int i = 1; i < 10; i++) myset.insert(i*20); it = myset....

Complexity Constant. Iterator validity All iterators, pointers and references referring to elements in both containers remain valid, and are now referring to the same elements they referred to before the call, but in the other container, where they now iterate. ...
erase: Erase elements (public member function ) clear: Clear content (public member function) swap: Swap content (public member function) Buckets bucket_count: Return number of buckets (public member function) max_bucket_count: Return maximum number of buckets (public member function) ...
