    Get info from Computer clock.

    I can use Clock() to get a pause in the system, But is there a function that actually works as a clock? I can make a Stopwatach thingy, but no buttons on top. But i really would like to have a function that gets the Day, Date Hours:Minutes:seconds from the PC clock. Is there a way to do that?

    There sure is :-)
    Code:
    #include <iostream>
    #include <ctime>
    
    using namespace std;
    
    int main()
    {
      time_t current;
    
      current = time(0);
    
      if (current != static_cast<time_t>(-1))
      {
        cout<< ctime(&current) <<flush;
      }
    }
    You can also use the tm struct and get more control over the content itself :-)
    Code:
    #include <iostream>
    #include <ctime>
    
    using namespace std;
    
    int main()
    {
      time_t current;
      struct tm *date;
      char datestr[1024];
      const char fmt[] = "%A %B %d, %y -- %I:%M:%S %p";
    
      current = time(0);
      date = localtime(&current);
    
      if (strftime(datestr, sizeof datestr, fmt, date) != 0)
      {
        cout<< datestr <<endl;
      }
    }
