How can I avoid deadlocks in C++?

To avoid deadlocks in C++, you can follow several strategies such as using a lock hierarchy, avoiding nested locks, and using timeout mechanisms.

What is a lock hierarchy?

A lock hierarchy is a method where you define a global order for acquiring locks. Always acquire locks in this predefined order to prevent circular wait conditions.

Can you give me an example of using a lock hierarchy?

Sure! If you have two locks, A and B, always acquire lock A before lock B in your code. This way, you avoid situations where one thread holds A and waits for B while another holds B and waits for A.

What are some other strategies to prevent deadlocks?

Other strategies include using try-lock mechanisms, implementing a timeout for lock acquisition, and avoiding holding multiple locks at once.
