22) Create a base class Conversion. Derive three different classes Weight (Gram, Kilogram), Volume(Milliliter, Liter), Currency(Rupees, Paise) from Conversion class. Write a C++ program to perform read, convert and display operations. (Use Pure virtual function).
#include<iostream.h>
#include<conio.h>
class conversion
{
public:
virtual void show()=0;
};
class weight:public conversion
{
int gm,kg;
public:
void get1()
{
cout<<"\n Enter Gram : ";
cin>>gm;
}
void show()
{
kg=gm/1000;
gm=gm % 1000;
cout<<"\n "<
}
};
class volume:public conversion
{
int ltr,mltr;
public:
void get2()
{
cout<<"\n Enter Milliliter : ";
cin>>mltr;
ltr=mltr % 1000;
mltr=mltr / 1000;
}
void show()
{
cout<<"\n "<
}
};
class currency:public conversion
{
float pse,rs;
public:
void get3()
{
cout<<"\n Enter Rupees : ";
cin>>rs;
pse=rs*100;
}
void show()
{
cout<<"\n Paise : "<
}
};
void main()
{
clrscr();
weight w;
volume v;
currency c;
conversion *p;
cout<<"\n Accept Info........";
w.get1();
v.get2();
c.get3();
cout<<"\n-----------------------------------";
