What are the differences between multi-threading and multi-processing in C++?

What are the differences between multi-threading and multi-processing in C++?

Multi-threading involves multiple threads within a single process sharing the same memory space, while multi-processing uses multiple processes with separate memory spaces.

Can you explain the advantages of each approach?

Sure! Multi-threading is generally more efficient in terms of memory usage and context switching, while multi-processing can provide better stability and fault isolation.

Which one is better for CPU-bound tasks?

For CPU-bound tasks, multi-processing is often better as it can utilize multiple CPU cores effectively, avoiding the Global Interpreter Lock (GIL) issues present in some languages.

Are there any specific libraries in C++ for implementing these?

Yes, for multi-threading, you can use the C++11 <thread> library, and for multi-processing, you might consider using libraries like Boost.Process.
