Question

1. Write the definition for a generic 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. Visual studio c++ is the language.
4. It should be a generic/template class not a simple class.

Answer 1

time.cpp

#include<iostream>
using namespace std;

// template class time
template <class T>
class time
{
   // data members
   T hours=0,minutes=0;
   public:
       // function to set time
       void setTime(T hour,T minute)
       {
           hours=hour;
           minutes=minute;
       }
       // function to display time
       void showTime()
       {
           cout<<"Hours: "<<hours<<" Minutes: "<<minutes<<endl;
       }
       // function to add two time objects and return it
       time Sum(time time1,time time2)
       {
           time<int> time3;
           time3.minutes=time1.minutes+time2.minutes;
           if(time3.minutes>=60)
           {
               time3.minutes-=60;
               time3.hours=time1.hours+time2.hours+1;
           }
           else
               time3.hours=time1.hours+time2.hours;
           return time3;
       }
};

// driver function
int main()
{
   // create time object
   time <int>time1;
   // set time to time object
   time1.setTime(10,25);
   time <int>time2;
   time2.setTime(5,45);
   time <int>time3;
   // call sum function to add 2 time objects
   time3=time3.Sum(time1,time2);
   // display all 3 time object
   time1.showTime();
   time2.showTime();
   time3.showTime();
   return 0;
}

Output
