What are the differences between thread synchronization and async in C++?
Thread synchronization ensures that multiple threads can safely access shared resources, while async allows tasks to run concurrently without blocking.
Can you give me an example of thread synchronization in C++?
Sure! You can use mutexes in C++ to synchronize threads. For example, using std::mutex
to protect shared data.
What about using async? How does that work?
Using std::async
, you can run a function asynchronously. It returns a future that you can use to get the result later.
When should I use synchronization over async?
Use synchronization when you need to protect shared resources. Use async for tasks that can run independently and benefit from concurrency.
