How can I improve performance in C++ using C++11 features?

How can I improve performance in C++ using C++11 features?

You can use features like move semantics, smart pointers, and the new concurrency support in C++11 to enhance performance.

Can you explain move semantics and how it helps with performance?

Move semantics allow resources to be transferred from one object to another without copying, reducing overhead and improving efficiency.

What are smart pointers and why should I use them?

Smart pointers manage memory automatically, preventing leaks and dangling pointers, which can lead to better performance and safer code.

Are there any specific examples of using concurrency features in C++11?

Yes, you can use std::thread for multithreading, std::async for asynchronous tasks, and std::mutex for thread safety.
