What are the performance improvements in C++11 standard iterators?

C++11 introduced several enhancements to standard iterators, including better efficiency and new types like 'std::move_iterator'. These changes help optimize performance in algorithms.

Can you explain how 'std::move_iterator' works?

Certainly! 'std::move_iterator' is a type of iterator that moves the elements from one container to another, rather than copying them. This is particularly useful for optimizing performance when dealing with temporary objects.

Are there any benchmarks comparing C++11 iterators to previous versions?

Yes, benchmarks generally show that C++11 iterators can be significantly faster due to reduced overhead and better memory management. However, the exact performance gain can vary based on the specific use case.

What other iterator types were introduced in C++11?

In addition to 'std::move_iterator', C++11 introduced 'std::back_inserter', 'std::front_inserter', and 'std::insert_iterator', which provide more flexibility in how elements are inserted into containers.
