Have you had experience using std::thread for multithreading?

Yes, I have used std::thread to create multithreaded applications in C++. This class from the standard library allows running functions in separate threads, which helps perform tasks in parallel.

Example of simple usage:

#include <iostream>
#include <thread>

void worker() {
    std::cout << "Thread is running\n";
}

int main() {
    std::thread t(worker); // create a thread that runs the worker function
    t.join(); // wait for the thread to finish
    return 0;
}

This approach allows parallelizing computations, improving performance on multi-core processors. It is important to manage threads properly to avoid data races and other synchronization issues.
