How do C++ set iterators work?

Can you explain how set iterators work in C++?

Sure! In C++, set iterators are used to traverse elements in a set. They provide a way to access each element in the set sequentially.

What are the different types of iterators available for sets?

There are two main types of iterators for sets: begin() and end(). begin() returns an iterator to the first element, while end() returns an iterator to one past the last element.

How do I use a set iterator in a loop?

You can use a for loop like this: for(auto it = mySet.begin(); it != mySet.end(); ++it) { /* access *it */ }.

Can I modify the elements of a set using iterators?

No, set iterators are constant iterators, meaning you cannot modify the elements they point to. Sets maintain unique elements.
