THE OUTPUT WOULD BE

#include<iostream.h>
#include<conio.h>
class A
{ float a1,a2,l,b,r;
public:
void B();
void C();
};
inline void A::B()
{       cout<<"Enter r:";
cin>>r;
a1=3.14*r*r;
cout<<"The area of circlr is "<<a1;
}
inline void A::C()
{       cout<<"Enter l=";
cin>>l;
cout<<"Enter b=";
cin>>b;
a2=l*b;
cout<<"The area of rectangle "<<a2;
}
void main()
{       int q;
clrscr();
cout<<"Press 1 for area of circle & Press 2 for area of rectangle\n";
cin>>q;
A obj;
switch(q)
{ case 1: obj.B();
 break;
 case 2: obj.C();
 break;
 default: cout<<"Wrong input";
  break;
}
getch();
