What is a mutex and how is it used in programming for multi-threading?

Absolutely, @dimplesaini.230 !

I completely agree. In my experience, a mutex is a synchronization tool used in multi-threaded programming to control access to resources. To build on what you said, imagine multiple threads trying to write to the same file, without a mutex, their writes could overlap and cause errors.

Using a mutex ensures that only one thread enters the critical section where the resource is accessed, while others wait, effectively serializing access to shared data. It’s the key to preventing those nasty bugs that crop up when things go out of order!
