How do I compare iterators in C++11?

Can you explain how to compare iterators in C++11?

Sure! In C++11, you can compare iterators using relational operators like ==, !=, <, >, <=, and >=.

What happens if I compare iterators from different containers?

Comparing iterators from different containers is undefined behavior, so you should avoid doing that.

Can you give me an example of comparing iterators?

Absolutely! Here's a simple example: if you have two iterators, it1 and it2, you can check if they point to the same element using if (it1 == it2) { /* same element */ }.

Are there any specific iterator types I should be aware of?

Yes, C++11 has several iterator types like input, output, forward, bidirectional, and random access, each with different capabilities.
