C++中的多线程迭代

#include <iostream>
#include <thread>
#include <vector>

// 定义迭代任务
void iterate(int start, int end) {
    for (int i = start; i <= end; ++i) {
        std::cout << "Thread " << std::this_thread::get_id() << ": " << i << std::endl;
    }
}

int main() {
    const int numThreads = 4; // 线程数量
    const int numIterations = 100; // 迭代次数

    std::vector<std::thread> threads;

    // 创建并启动多个线程
    for (int i = 0; i < numThreads; ++i) {
        int start = i * (numIterations / numThreads) + 1;
        int end = (i + 1) * (numIterations / numThreads);
        threads.emplace_back(iterate, start, end);
    }

    // 等待所有线程执行完毕
    for (auto& thread : threads) {
        thread.join();
    }

    return 0;
}
