C++ 20 (2a) New Features - Latches and Barriers

The video tutorial explains the use of synchronization mechanisms like latches and barriers in multithreading. It starts with an example using a latch, where two threads increment a counter and wait for each other to finish before proceeding. The tutorial then transitions to barriers, highlighting their reusability and flexibility compared to latches. The concept of a flex barrier, which allows runtime modification of the counter, is also introduced.
