What are the performance issues with C++11 iterators?
C++11 iterators can have performance issues due to overhead from abstractions, especially with complex data structures.
Can you explain how these overheads affect performance?
Sure! The overhead can lead to increased memory usage and slower access times, particularly in nested or chained iterators.
Are there specific types of iterators that are more efficient?
Yes, for example, using random access iterators can be more efficient than input or output iterators in certain scenarios.
What are some best practices to mitigate these performance issues?
To mitigate issues, prefer using algorithms that minimize iterator usage, and consider using pointers for direct access when possible.
