Question

1. Write the definition for a generic / Template class called time that has hours and minutes as structure. The class has the following member functions:
   SetTime to set the specified value in object
   ShowTime to display time object
   Sum to sum two time object & return time

1. Write the definitions for each of the above member functions.
2. Write main function to create three time objects. Set the value in two objects and call sum() to calculate sum and assign it in third object. Display all time objects.
3. The language is Visual studio c++
