What is the std thread library and how does synchronization work?

What is the std thread library in C++?

The std thread library in C++ provides a way to create and manage threads, allowing for concurrent execution of code.

How does synchronization work in this library?

Synchronization in the std thread library is achieved using mutexes, condition variables, and other synchronization primitives to prevent data races.

Can you give an example of using a mutex?

Sure! You can use std::mutex to protect shared data. For example, lock the mutex before accessing the data and unlock it afterward.

What happens if I forget to unlock a mutex?

If you forget to unlock a mutex, it can lead to deadlocks, where other threads are unable to proceed because they are waiting for the mutex to be released.
