Linux中C++程序如何实现多线程

#include <iostream>
#include <pthread.h>
<p>// 线程函数
void<em> thread_function(void</em> arg) {
int thread_id = <em>(static_cast<int</em>>(arg));
std::cout << "Thread ID: " << thread_id << std::endl;
return nullptr;
}</p><p>int main() {
pthread_t threads[5];
int thread_ids[5] = {1, 2, 3, 4, 5};</p><pre class="brush:php;toolbar:false">for (int i = 0; i < 5; ++i) {
    pthread_create(&threads[i], nullptr, thread_function, &thread_ids[i]);
}

for (int i = 0; i < 5; ++i) {
    pthread_join(threads[i], nullptr);
}

return 0;

#include <iostream>
#include <thread>
#include <vector>
<p>// 线程函数
void thread_function(int thread_id) {
std::cout << "Thread ID: " << thread_id << std::endl;
}</p><p>int main() {
std::vector<std::thread> threads;</p><pre class="brush:php;toolbar:false">for (int i = 0; i < 5; ++i) {
    threads.emplace_back(thread_function, i + 1);
}

for (auto& thread : threads) {
    thread.join();
}

return 0;
