Thread: How to let the second run?

How to let the second run (that mean always change the number of second) when run the program?

Code:

time_t today;	
time(&today);
struct tm*date=localtime(&today);
int d=date->tm_mday;
int m=date->tm_mon+1;
int y=date->tm_year+1900;
int h=date->tm_hour;
int t=date->tm_min;
int s=date->tm_sec;
cout<<"\nDate: "<<d<<"/"<<m<<"/"<<y;
cout<<"\t\tTime: "<<h<<":"<<t<<":"<<s;

You mean constantly update the seconds?

Code:

while(Running)
{
  Seconds++; //Increase seconds
  std::cout << Seconds; //Print seconds
  sleep(1); //Sleep 1 second until next update
}

you could also do it this way if you don't want to use the Sleep() function...

Code:

while(running)
{
     timer=clock();
     if(timer%1000==0)
          std::cout<<timer<<" "<<std::flush;
}

by the way, sleep has a capital 'S'

If I'm not entirely mistaken, sleep(t) (tiny s) sleeps for t seconds, while Sleep(t) (capital S) sleeps for r milliseconds. The latter requires windows.h.

sleep actually sleeps the calling thread, while your solution still puts a heavy load on the CPU though a death loop.

yeah, your right... I forgot about the sleep with a lowercase 's'... and my method is very CPU intensive, but I don't know about the portability of the sleep code...
