What are the advanced features of C++11's std::set?

C++11's std::set includes features like initializer lists, emplace, and improved performance with move semantics.

Can you explain how initializer lists work with std::set?

Sure! Initializer lists allow you to initialize a std::set with a list of values directly, like this: std::set<int> mySet = {1, 2, 3};.

What is the emplace function and how does it differ from insert?

The emplace function constructs an element in-place, which can be more efficient than insert, as it avoids unnecessary copies.

How do move semantics improve performance in std::set?

Move semantics allow std::set to transfer ownership of resources instead of copying them, reducing overhead and improving performance.
