What are the performance characteristics of C++11 standard algorithms?

C++11 introduced several standard algorithms that are optimized for performance. They often use move semantics and lambda expressions, which can lead to significant improvements in efficiency.

Can you give examples of specific algorithms and their performance?

Sure! For instance, std::sort is highly optimized and typically runs in O(n log n) time. std::for_each can be very efficient with lambda functions, especially when used with move semantics.

How do these algorithms compare to their predecessors?

Many C++11 algorithms outperform their predecessors due to better memory management and the introduction of features like concurrency. For example, std::copy can be more efficient with move semantics.

Are there any trade-offs I should be aware of?

Yes, while C++11 algorithms are generally faster, they may have increased complexity in terms of understanding and using features like lambda expressions and move semantics.
