Write an oop to create a class named “Time” with data objects and two member functions to add two member functions to add two times and display the resultant time. You must demonstrate returning object from the function that will add two times.

Source code:

//program to add and display two Time objects

#include <iostream>
using namespace std;

class Time{
    private:
        int hh;
        int mm;
        int ss;
    public:
        //parameterized constructor, with default argument to initialize time
        //or make a function to read time
        Time(int h =0,int m = 0, int s = 0){
            hh = h;
            mm = m;
            ss = s;
        }
        //function to add and return time object
        Time add(Time t1){
            Time temp;
            temp.ss = ss + t1.ss;
            temp.mm = mm + t1.mm;
            temp.hh = hh + t1.hh;

            //implement mechanism to convert time in proper format
            if(temp.ss >= 60){
                temp.mm += temp.ss / 60;
                temp.ss = temp.ss % 60;
            }
            if(temp.mm >= 60){
                temp.hh += temp.mm / 60;
                temp.mm = temp.mm % 60;
            }
            return temp;
        }
        void display(){
            cout<<"HH:MM:SS = "<<hh<<":"<<mm<<":"<<ss<<endl;
        }
};


int main(){
    Time t1(4,35,55), t2(5, 10, 15), t3;
    cout<<"Two times are:"<<endl;
    t1.display();
    t2.display();
    t3 = t1.add(t2);
    cout<<"SUM is:"<<endl;
    t3.display();
    return 0;
}

Sample run:

Two times are:
HH:MM:SS = 4:35:55
HH:MM:SS = 5:10:15
SUM is:
HH:MM:SS = 9:46:10
