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 what a data race is?

A data race occurs when two or more threads access shared data simultaneously, and at least one of the accesses is a write. This can lead to unpredictable behavior.

How can I avoid data races?

You can avoid data races by using synchronization mechanisms like mutexes, locks, or atomic operations to control access to shared data.

What are mutexes and how do I use them?

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