Create two classes dm and db which store the value of distances with out put
Answers
Write a program that can read values for the class objects and add one object DM with another object of DB. Use a Friend Function to carry out the addition operation. The object that stores the results may be a DM object or DB object, depending on the units in which the
Coding:
#include<iostream.h>
#include<conio.h>
class DB;
class DM
{
float meter,centi;
public:
void getdata()
{
cout<<"\nEnter the distance in(meter-centimeter):";
cin>>meter>>centi;
}
void display()
{
cout<<"\nThe distance is:";
cout<<meter<<" meters and "<<centi<<" centimeter";
}
friend void add(DM &,DB &);
};
class DB
{
float inch,feet;
public:
void getdata()
{
cout<<"\nEnter the distance in(feet-inch):";
cin>>feet>>inch;
}
void display()
{
cout<<"\nThe distance is:";
cout<<feet<<" feet and "<<inch<<" inch";
}
friend void add(DM &,DB &);
};
void add(DM &a,DB &b)
{
int ch;
cout<<"\nPress 1 for meter-centi:";
cout<<"\nPress 2 for feet-inch:";
cout<<"\nEnter your choice:";
cin>>ch;
if(ch==1)
{
DM d;
int c=(a.meter*100+a.centi+b.feet*30.48+b.inch*2.54);
if(c>=100)

d.meter=c/100;
d.centi=c%100;

d.centi=c;
