How do iterator adaptors in C++11 affect performance?

How do iterator adaptors in C++11 affect performance?

Iterator adaptors in C++11 can improve performance by enabling lazy evaluation and reducing the need for temporary containers.

Can you give an example of using an iterator adaptor?

Sure! For instance, using std::transform with an iterator adaptor can apply a function to elements without creating a new container.

Are there any performance drawbacks to using them?

Yes, while they can be efficient, excessive use of adaptors can lead to increased complexity and potential overhead in some cases.

How do they compare to traditional iterators?

Iterator adaptors provide more flexibility and can lead to cleaner code, but traditional iterators may be more straightforward in some scenarios.

What are some best practices when using iterator adaptors?

Best practices include keeping the code readable, avoiding deep nesting of adaptors, and profiling performance to ensure efficiency.
