What are the advanced set operations in C++11?

Can you explain the advanced set operations available in C++11?

Sure! C++11 introduced several advanced set operations in the Standard Template Library (STL), such as union, intersection, and difference.

How do I perform a union operation on two sets?

You can use the std::set_union algorithm, which combines two sorted sets into a new set. Here's a quick example.

What about intersection? How is that done?

For intersection, you can use std::set_intersection. It takes two sorted sets and outputs the common elements into a new set.

Are there any performance considerations I should be aware of?

Yes, the performance can vary based on the size of the sets and the operations used. Generally, these operations are efficient with logarithmic complexity.
