#include <iostream>


class Time {
  private:
    int hours;
    int minutes;
    int seconds;
  public:
    Time() : hours(0), minutes(0), seconds(0) {}
    Time(int _hours, int _minutes, int _seconds)
      : hours(_hours), minutes(_minutes), seconds(_seconds) {}
    friend std::ostream& operator <<(std::ostream& os, const Time& time) {
      if (time.hours / 10 == 0) {
        os << "0";
      }
      os << time.hours << ":";
      if (time.minutes / 10 == 0) {
        os << "0";
      }
      os << time.minutes << ":";
      if (time.seconds / 10 == 0) {
        os << "0";
      }
      os << time.seconds;
      return os;
    }
    ~Time() {}
};


int main() {
  int hours, minutes, seconds;
  std::cout << "Enter hours, minutes, seconds separated with space:\n";
  std::cin >> hours >> minutes >> seconds;
  Time t(hours, minutes, seconds);
  std::cout << t << '\n';
  return 0;
