When should I use lock-based algorithms?

When should I use lock-based algorithms in my code?

Lock-based algorithms are useful when you need to ensure that only one thread can access a resource at a time to prevent data corruption.

Can you give me an example of a situation where this would be necessary?

Sure! For instance, if multiple threads are trying to update a shared bank account balance, using locks can prevent inconsistent states.

Are there any downsides to using lock-based algorithms?

Yes, they can lead to issues like deadlocks and reduced performance due to thread contention, so they should be used judiciously.

What are some alternatives to lock-based algorithms?

Alternatives include lock-free algorithms, optimistic concurrency control, and using higher-level abstractions like semaphores.
