C++ Standard Template Library in Practice - Async

The video tutorial introduces the concepts of promises and futures in C++, explaining how they facilitate asynchronous programming by allowing threads to communicate results without shared memory. The tutorial includes a code demonstration that generates a large dataset, divides it among multiple threads, and sums the results using promises and futures. The video concludes with a demonstration of CPU usage during execution and a preview of the next topic, condition variables.

Describe how the partial sum function works in the context of threading.

What happens when multiple futures finish at roughly the same time?

How does the program demonstrate CPU utilization when running the vector generation?
