Can you explain the thread lifecycle in C++?

Can you explain the thread lifecycle in C++?

Sure! The thread lifecycle in C++ involves several states: new, runnable, blocked, waiting, and terminated.

What happens in each of these states?

In the new state, a thread is created but not yet started. In runnable, it's ready to run. Blocked means it's waiting for a resource, while waiting indicates it's waiting for another thread to perform a specific action. Finally, terminated means the thread has completed its execution.

How do I create and manage threads in C++?

You can use the <thread> library. To create a thread, you instantiate a std::thread object and pass it a function to execute. You can manage threads using methods like join() and detach().

Can you give me a code example?

Certainly! Here's a simple example:

#include <iostream>
#include <thread>

void threadFunction() {
    std::cout << "Thread is running!" << std::endl;
}

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