What are the benefits of using lock_guard?

What are the benefits of using lock_guard in C++?

Using lock_guard in C++ helps manage mutexes automatically, ensuring that locks are released when they go out of scope.

Can you explain how it prevents deadlocks?

lock_guard prevents deadlocks by ensuring that locks are acquired and released in a consistent order, reducing the chances of circular wait.

Are there any performance implications?

Generally, lock_guard has minimal overhead, but excessive locking can lead to contention, which may affect performance.

What happens if an exception is thrown?

If an exception is thrown, lock_guard ensures that the mutex is still released, preventing resource leaks and maintaining safety.

Is lock_guard suitable for all scenarios?

While lock_guard is great for most cases, for more complex locking strategies, you might need other synchronization mechanisms.
