A deadlock in C++ threading occurs when two or more threads are blocked forever, each waiting for the other to release a resource.

Can you give me an example of a deadlock situation?

MagicBuddy

Sure! Imagine two threads: Thread A locks Resource 1 and then tries to lock Resource 2, while Thread B locks Resource 2 and then tries to lock Resource 1. They end up waiting for each other indefinitely.
