【Description】

Write a program to define a class Time, which contains three member variables: hour, minute and second

Please realize the following functions with operator overloading:

  • input and output time with >> and <<

  • use += and -= increase and decrease the time ，e.g.Time& operator+=(const Time&);Time& operator-=(const Time&)；

     

【Input】

  • There are two line, each line is the time of a clock

  • Input format：hour minute second。

【Output】

  • There are two lines.

  • The first line is the output of time1 += (time2) ;

  • The second line is the output of time1 -= time2 ;

  • Output format：hour:minute:second；

  • Please read the 

【Input example】

21 10 35

10 15 25

【Output example】

07:26:00

21:10:34
