CODE EXAMPLE FOR CPP

C++ sleep for seconds

#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;
