Create a class time which stores time in hours, minutes and seconds. Use necessary member functions to get and display the information. Finally define a member function sum that takes the two input time as hrs:min:sec and add the two time and assign to third time i.e. t3=t1+t2. Note that 60sec=1 min and 60mins= 1 hr.

ALGORITHM:

1.      Declare class time

2.      get(int,int,int)

i.                    set hrs =h, min=m,secs=s

3.      put()

ii.                  display hrs:min:secs

4.      sum(time,time)

sec=t1.sec+t2.sec;

                        min=t1.min+t2.min;

                        if (sec>=60)

                        {

                                    min++;

                        }

                        hr=t1.hr+t2.hr;

                        if (min>=60)

                        {

                                    hr++;

                        }

                        sec=sec%60;

                        min=min%60;

                        hr=hr%12;

5.      main()

                                i.            t1.get(h,m,s)

                              ii.            t2.get(h,m,s)

                            iii.            t3.sum(t1,t2)

                            iv.            t1.put()

                              v.            t2.put()

                            vi.            t3.put()

6.      end
