Nettet14. mai 2013 · Because C++ sets are ordered by the T 's comparison operator, which makes it possible to iterate over the members in a predictable way. If you know that all you will do with the set is insert, test membership, and/or remove elements, then std::unordered_set, which implements a hashset, exists for that since C++11. Share … NettetSets are containers that store unique elements following a specific order.

"Nettet28. sep. 2009 · The exact implementation is therefore a bit of a secret. It's not complex though. It's basically an object that has a boolean field, which it gets and sets. When using a counter, it can become a Semaphore. A mutex is the starting point for a critical section, which uses a mutex internally to see if it can enter a section of code.
