What are some examples of multithreading in C++?

Multithreading in C++ allows concurrent execution of tasks. Examples include using the <thread> library to create threads for parallel processing.

Can you show me a simple code example?

Sure! Here's a basic example:

#include <iostream>
#include <thread>

void printHello() {
    std::cout << "Hello from thread!" << std::endl;
}

int main() {
    std::thread t(printHello);
    t.join(); // Wait for the thread to finish
    return 0;
}

What are the benefits of using multithreading?

Benefits include improved performance, better resource utilization, and responsiveness in applications, especially in I/O-bound tasks.

Are there any challenges with multithreading?

Yes, challenges include race conditions, deadlocks, and increased complexity in debugging and maintaining code.
