What are the best practices for using threads in C++?

When using threads in C++, it's important to follow best practices like avoiding data races, using mutexes for synchronization, and ensuring proper resource management.

Can you explain how to avoid data races?

To avoid data races, ensure that shared data is accessed by only one thread at a time. Use mutexes or other synchronization mechanisms to protect shared resources.

What are mutexes and how do I use them?

Mutexes are mutual exclusion objects that prevent multiple threads from accessing shared data simultaneously. You can use std::mutex in C++ to lock and unlock access to shared resources.

Are there any alternatives to mutexes?

Yes, alternatives include using std::atomic for simple data types, or higher-level constructs like std::lock_guard and std::unique_lock for easier management of mutexes.
