What are the performance improvements in C++11 iterators?
C++11 introduced several enhancements to iterators, including move semantics and better support for range-based for loops.
Can you explain how move semantics affect iterator performance?
Move semantics allow resources to be transferred rather than copied, reducing overhead and improving performance when using iterators.
Are there specific types of iterators that benefit the most from these improvements?
Yes, particularly move-only types like std::unique_ptr
see significant benefits, as they can be moved without copying.
How do these changes compare to previous versions of C++?
Compared to C++98/03, C++11's iterators are more efficient due to reduced copying and better integration with modern C++ features.
