How do I handle exceptions in C++ threads?

In C++, you can handle exceptions in threads using try-catch blocks. Wrap your thread function in a try block and catch exceptions in the thread's main function.

Can you show me a code example?

Sure! Here's a simple example:

#include <iostream>
#include <thread>
#include <stdexcept>

void threadFunction() {
    throw std::runtime_error("Error in thread");
}

int main() {
    try {
        std::thread t(threadFunction);
        t.join();
    } catch (const std::exception &e) {
        std::cout << "Caught exception: " << e.what() << std::endl;
    }
    return 0;
}

What happens if I don't catch the exception?

If you don't catch the exception, it will terminate the program and may lead to resource leaks or undefined behavior.

Are there any best practices for exception handling in threads?

Yes, some best practices include always catching exceptions, using futures for exception propagation, and ensuring thread safety.
