在C ++中暂停程序执行5秒钟 [英] Pause program execution for 5 seconds in c++

问题描述

我想将c ++程序的执行暂停5秒钟。在android中，Handler.postDelayed具有所需的功能，我正在寻找。

I want to pause the execution of c++ program for 5 seconds. In android Handler.postDelayed has the required functionality what I am looking for. Is there anything similar to that in c++?

推荐答案

#include <iostream>
#include <chrono>
#include <thread>

int main()
{
    std::cout << "Hello waiter" << std::endl;
    std::chrono::seconds dura( 5);
    std::this_thread::sleep_for( dura );
    std::cout << "Waited 5s\n";
}

this_thread :: sleep_for 至少在指定的sleep_duration内阻止当前线程的执行。

this_thread::sleep_for Blocks the execution of the current thread for at least the specified sleep_duration.
