Write a c++ program for finding the area and circumference of a circle when radius of the circle is given. include necessary data members and member function.

#include<iostream.h>
#include<conio.h>
class circle
{
private:
int radius;
float area,circum;
public:
void getRadius()
{
cout<<"Enter Radius";
cin>>radius;
}
void calculate()
{
area=(float)3.14*radius*radius;
circum=2*3.14*radius;
}
void print()
{
cout<<"Details of the given circle\n";
cout<<"------------------------------\n";
cout<<"Radius  :"<<radius<<"\n";
cout<<"Area   :"<<area<<"\n";
cout<<"Circumference:"<<circum<<"\n";
cout<<"----------------------\n";
}
};
void main()
{
clrscr();
circle C;
C.getRadius();
C.calculate();
C.print();
getch();
}

Output:
Enter Radius4
Details of the given circle
-----------------------------
Radius :4
Area   :50.240002
Circumference:25.120001
-------------------------------
