What are some alternatives to using mutex in C++?

There are several alternatives to mutex in C++, such as using atomic operations, read-write locks, or condition variables. Each has its own use cases.

Can you explain how atomic operations work?

Atomic operations are low-level operations that complete in a single step relative to other threads. They help avoid race conditions without the overhead of mutexes.

What about read-write locks? When should I use them?

Read-write locks allow multiple threads to read data simultaneously while ensuring exclusive access for writing. They're useful when reads are more frequent than writes.

Are there any performance considerations I should be aware of?

Yes, while alternatives can improve performance, they also introduce complexity. It's essential to analyze your specific use case to choose the right synchronization method.
