#include<iostream.h>

#include<conio.h>

class distance

          {

          private :

                   int mts ;

                   int cms;

          public :

                   void init (int a, int b)

                             {

                             mts=a; cms = b;

                             }

Out put

          Enter a distance in meters and cms : 7                 65

          The two distances are:

          7 Meters 65 Centimeters

          And

          5 Meters 85 Centimeters

          Sum is

13 Meters 50 Centimeters.
