C++ pause program

#include <iostream>
#include <unistd.h>     //required for usleep()
using namespace std;
int main(){
    //usleep will pause the program in micro-seconds (1000000 micro-seconds is 1 second)
    const int microToSeconds = 1000000;   
    const double delay1 = 2 * microToSeconds;     //2 seconds
    const double delay2 = 4.5 * microToSeconds;     //4.5 seconds
    
    cout<<"Delay 1 in progress... ("<<delay1/microToSeconds<<"s)"<<endl;
    usleep(delay1);        
    cout<<"  => Delay 1 is over"<<endl<<endl;
    
    cout<<"Delay 2 in progress... ("<<delay2/microToSeconds<<"s)"<<endl;
    usleep(delay2);
    cout<<"  => Delay 2 is over"<<endl<<endl;

    return 0;
}

c++ pause

#include <Windows.h>

int main() {
	//do stuff
	system("Pause");
}

How to pause a c++ program.

//On windows.
#include<windows.h>
Sleep(milliseconds);

//On linux.
#include<unistd.h>
unsigned int microsecond = 1000000;
usleep(3 * microsecond);//sleeps for 3 second

// c++ 11 for high resulution.

#include <chrono>
#include <thread>

int main() {
    using namespace std::this_thread; // sleep_for, sleep_until
    using namespace std::chrono; // nanoseconds, system_clock, seconds

    sleep_for(nanoseconds(10));
    // or 
    sleep_until(system_clock::now() + seconds(1));
}

// C++ 14 for high resuluton.

#include <chrono>
#include <thread>

int main() {
    using namespace std::this_thread;     // sleep_for, sleep_until
    using namespace std::chrono_literals; // ns, us, ms, s, h, etc.
    using std::chrono::system_clock;

    sleep_for(10ns);
  	// or
    sleep_until(system_clock::now() + 1s);
}

c++ pause

system("pause");
