What is the C++ thread library and how do I use it?

The C++ thread library provides tools for creating and managing threads in C++. It allows for concurrent execution of code.

Can you give me an example of creating a thread?

Sure! You can create a thread using the std::thread class. Here's a simple example:

#include <iostream>
#include <thread>

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

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

What does t.join() do?

The t.join() function blocks the calling thread until the thread represented by t has finished executing. It's essential for ensuring that the main thread waits for the new thread to complete.

Are there any potential issues with using threads?

Yes, using threads can lead to issues like race conditions, deadlocks, and resource contention. It's important to manage shared resources carefully.
