在For循环c++中创建线程

#include <iostream>
#include <thread>

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

int main() {
    int numThreads = 5;
    std::thread threads[numThreads];

    for (int i = 0; i < numThreads; i++) {
        threads[i] = std::thread(threadFunction, i);
    }

    for (int i = 0; i < numThreads; i++) {
        threads[i].join();
    }

    return 0;
}
