What are the main differences between the C++ thread library and async?
The C++ thread library provides low-level control over threads, while async offers a higher-level abstraction for asynchronous tasks.
Can you give me an example of using the thread library?
Sure! You can create a thread using std::thread
and pass a function to it. For example: std::thread t(myFunction);
.
How does async handle exceptions compared to threads?
Async can catch exceptions in the future object it returns, while exceptions in threads need to be handled within the thread function.
Which one is better for performance?
It depends on the use case. Threads can be more efficient for CPU-bound tasks, while async is better for I/O-bound tasks.
