Complete Modern C++ - Propagating Exceptions Across Threads

The video tutorial explains how promises can be used to propagate exceptions between threads. It covers setting exceptions in promises using try-catch blocks and the creation of exception pointers for sharing exceptions across threads. The tutorial demonstrates exception propagation from the main thread to a task and vice versa, highlighting the automatic creation of exception pointers by the runtime. It concludes by emphasizing the utility of promises for data sharing between threads without manual synchronization.

Explain the process of throwing an exception in a task and how it affects the main thread.

What advantages do promises provide for sharing data between threads compared to manual thread synchronization?
