C++ Thread Synchronization Methods

In C++, there are various methods for synchronizing multithreading, commonly used options include:

1. Mutex: Use classes such as std::mutex or std::lock_guard to protect shared resources, ensuring that only one thread can access the shared resource at a time.
2. Condition variables enable communication and synchronization between threads using classes such as std::condition_variable or std::unique_lock, allowing operations to be executed only when a certain condition is met.
3. Atomic operation: Using classes like std::atomic or std::atomic_flag to manipulate shared variables, ensuring that operations on shared variables by multiple threads are atomic and do not result in race conditions.
4. Semaphore: Control the order and quantity of access for multiple threads using std::semaphore or a third-party library.
5. Read-Write Lock: Improve the concurrency performance of read operations by implementing a read-write lock using std::shared_mutex or a third-party library.

These methods can be chosen based on specific needs and scenarios to implement multi-thread synchronization.
