What are the best practices to avoid deadlocks in C++?

To avoid deadlocks in C++, you can follow these best practices: 1. Use a consistent locking order, 2. Use timeouts when acquiring locks, 3. Avoid holding multiple locks at once, and 4. Use lock-free data structures when possible.

Can you explain the consistent locking order?

Sure! A consistent locking order means that all threads should acquire locks in the same predefined order. This prevents circular wait conditions, which are a common cause of deadlocks.

What are lock-free data structures?

Lock-free data structures are designed to allow multiple threads to operate on them without the need for locks, reducing the chances of deadlocks and improving performance.

Are there any libraries in C++ that support lock-free programming?

Yes, C++ provides several libraries for lock-free programming, such as the C++11 standard library's atomic types and Boost's lock-free data structures.
