What are unordered_map iterators in C++?

Can you explain what unordered_map iterators are in C++?

Sure! Unordered_map iterators are used to traverse elements in an unordered_map, which is a hash table-based container.

How do I use these iterators to access elements?

You can use the begin() and end() methods to get iterators to the first and one-past-the-last elements, respectively.

Are there different types of iterators for unordered_map?

Yes, unordered_map provides forward iterators, which allow you to traverse the elements in a single direction.

Can I modify the elements while iterating?

Yes, you can modify the elements using the iterator, but be cautious as it may affect the structure of the unordered_map.
