What is the difference between std::unique_lock and std::lock_guard?

Can you explain the difference between std::unique_lock and std::lock_guard in C++?

Sure! Both std::unique_lock and std::lock_guard are used for managing mutexes in C++, but they have some key differences.

What are the main features of std::unique_lock?

std::unique_lock provides more flexibility; it can be locked and unlocked multiple times, and it can be used with condition variables.

And what about std::lock_guard?

std::lock_guard is simpler and provides a scoped lock that automatically unlocks when it goes out of scope, but it cannot be unlocked manually.

When should I use one over the other?

Use std::lock_guard for simple locking scenarios, and std::unique_lock when you need more control over the locking mechanism.
