Classes With Primitive Data Members in OOPS in c++ how to implment Class Primitve Data Member

In these primitive data Member we use the void AREA::circle(int r) , void AREA::rectangle(int l,int b) function by using these function we can implement Classes with primitive Data Members in C++ programming OOPS
Source code in c++ Programming OOPS
#include<iostream.h>
#include<conio.h>
#define pi 3.14
class AREA
{
int area1,area2;
public:
void circle(int r);
void rectangle(int l,int b);
};
void AREA::circle(int r)
{
area1=pi*r*r;
cout<<"AREA OF THE CIRCLE : "<<area1;
}
void AREA::rectangle(int l,int b)
{
area2=l*b;
cout<<"AREA OF THE RECTANGLE : "<<area2;
}
void main()
{
int r,l,b;
clrscr();
AREA JJ;
cout<<"\nEnter the radius of the circle : ";
cin>>r;
JJ.circle(r);
cout<<"\n\nEnter the length & breadth of the rectangle : ";
cin>>l>>b;
JJ.rectangle(l,b);
getch();
}

OUTPUT c++ programming for oops
Enter the radius of the circle : 7
AREA OF THE CIRCLE : 153
Enter the length & breadth of the rectangle : 15 7
AREA OF THE RECTANGLE : 105
