What are some examples of C++ threading?

Can you give me some examples of threading in C++?

Sure! In C++, you can use the <thread> library to create and manage threads. For example, you can create a thread like this:

#include <iostream>
#include <thread>

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

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

What does t.join() do in that example?

The t.join() function call makes the main thread wait for the thread t to finish executing before continuing. This ensures that the program doesn't terminate before the thread has completed its task.

Are there any potential issues with using threads?

Yes, there are several issues to consider, such as race conditions, deadlocks, and resource contention. It's important to use synchronization mechanisms like mutexes to avoid these problems.

Can you explain what a race condition is?

A race condition occurs when two or more threads access shared data and try to change it at the same time. If the access is not properly synchronized, it can lead to unpredictable results.
