I have the following code:
set<Key> test;
test.insert(key1);
test.insert(key2);
iter1 = test.find(key1);
iter2 = test.find(key2);
test.erase(iter1);
My question is, if key1 is deleted, now can I use iter2 to refer to key2 in test?
Thanks
Yes, set’s
eraseinvalidates only iterators that point to the element that was erased (note that this is not necessarily true for all containers).
