async: Start Policy
Explore how std::async start policies control whether asynchronous tasks run immediately or are deferred in C++. Understand the difference between eager and lazy evaluation and how to use them for efficient multithreading with futures and promises. This lesson helps you grasp managing task execution timing for better resource use in concurrent programming.

With the start policy, we can explicitly specify whether the asynchronous call should be executed in the same thread (std::launch::deferred) or in another thread (std::launch::async).
i Eager versus lazy evaluation
Eager and lazy evaluations are two orthogonal strategies to ...
