C++ Program Using Friend Class-Add Two Time Together.

This is a sample program using Friend Classes. Using Friend Classes, here we add two different time together & display the final time.


#include <iostream.h>
#include <conio.h>

class time
{
    private:
       int h, m, s;

    public:

       void read()
         {
             cout<<"Enter Time In Hours:Minutes:Seconds \n";
             cin>>h>>m>>s;
         }

       friend void add(time t1, time t2, time t3)
         {
             t3.h=t1.h+t2.h;
             t3.m=t1.m+t2.m;
             t3.s=t1.s+t2.s;

             if (t3.s>=60)
               {
                   t3.m+=t3.s/60;
                   t3.s=t3.s%60;
               }

             if(t3.m>=60)
               {
                   t3.h+=t3.m/60;
                   t3.m=t3.m%60;
               }

             cout<<"\n New Time:"<<t3.h<<" Hours "<<t3.m<<" Minutes "<<t3.s<< " Seconds ";
         }

};

void main()
{
    clrscr();
    time t1,t2,t3;
    t1.read();
    t2.read();
    add(t1,t2,t3);
    getch();
}


OUTPUT:

Enter Time In Hours:Minutes:Seconds
9
20
10

Enter Time In Hours:Minutes:Seconds
1
20
5

New Time: 10 Hours 40 Minutes 15 Seconds
