What are some effective concurrency techniques in C++?

In C++, effective concurrency techniques include using threads, mutexes, condition variables, and the C++11 standard library features.

Can you explain how to use mutexes for thread safety?

Sure! A mutex (mutual exclusion) is used to protect shared data from being accessed by multiple threads simultaneously. You can lock a mutex before accessing shared data and unlock it afterward.

What are condition variables and how do they work?

Condition variables are synchronization primitives that allow threads to wait until a particular condition occurs. They are used in conjunction with mutexes to avoid busy waiting.

Are there any best practices for using threads in C++?

Yes, some best practices include minimizing shared data, using RAII for resource management, and avoiding deadlocks by following a consistent locking order.
