C++ Thread Exercise #1 | Thread Creation

Thread Exercise: Write a program that creates a simple thread in C++.

Solution:

#include <iostream>
#include <thread>

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

int main() {
    std::thread t(threadFunction);
    t.join();
    std::cout << "Main thread exiting..." << std::endl;
    return 0;
}

Explanation:

• We define a function threadFunction() which will be executed by the thread.
• In the main() function, we create a thread t and pass threadFunction to its constructor.
• We use t.join() to wait for the thread to finish execution before the main thread exits.
