Advanced C++ Concurrency

Implement lock-free operations using `std::atomic` and explain the concept of atomicity.

Analyze different memory ordering options (`relaxed`, `acquire-release`, `seq_cst`) and their performance implications.

Identify and mitigate false sharing by analyzing cache line behavior in multi-core systems.

Use `std::promise` and `std::future` to transfer data asynchronously between threads.

Use `std::packaged_task` and `std::async` to simplify the management of asynchronous operations.

Implement a reader-writer lock using `std::shared_mutex` for scenarios with frequent reads and infrequent writes.

Analyze the internal mechanics of `std::promise` and `std::future`, including their shared state.

Compare the trade-offs between lock-based and lock-free concurrency.
