How do I use std::set in C++?

Can you explain how to use std::set in C++?

Sure! std::set is a part of the C++ Standard Library that stores unique elements in a specific order. It automatically sorts the elements and ensures that no duplicates are stored.

What are the main features of std::set?

The main features include automatic sorting, unique elements, and efficient search operations. It uses a balanced tree structure for these operations.

You can insert elements using the insert() method. For example: mySet.insert(value); will add 'value' to the set if it's not already present.

Can I iterate over the elements in a std::set?

Yes, you can use a range-based for loop or an iterator to iterate over the elements. For example: for (const auto& elem : mySet) { /* process elem */ }.
