How do C++14 standard library iterators perform compared to previous versions?

What improvements were made to the C++14 standard library iterators?

C++14 introduced several enhancements, including better performance optimizations and new iterator types.

Can you explain how these improvements affect performance?

The optimizations reduce overhead, making operations like traversal and manipulation faster, especially in complex data structures.

Are there specific benchmarks available to compare these iterators?

Yes, various benchmarks show that C++14 iterators can outperform those from C++11 in many scenarios, particularly with algorithms.

What are some best practices for using these iterators effectively?

It's best to use them in conjunction with algorithms from the standard library and to prefer range-based for loops for clarity.
