Semaphores are a powerful way to manage thread synchronization in C/C++ when you need to control access to limited resources. Unlike a mutex, a semaphore can allow multiple threads to proceed—think of it as a counter! With CreateSemaphore() on Windows or sem_t in POSIX, you set how many threads can access a resource at once. It’s ideal for scenarios like limiting concurrent connections or managing a thread pool.
