Help with Classes

Im wondering on how i would display the "area" in main?


#include <iostream>
#include <string>
using std::cout;
using std::cin;
using std::endl;
using std::string;

class Circle
{ private:
double radius;

public:
void setRadius (double r)
{radius=r;}
double getArea()
{return 3.14*pow(radius,2);}

int main () {


return 0;
}

How can you get as far as to write a class, several #include and using statements (which involve the objects that answer your question) and ask how to print something to the screen? Are you reading from a book or did you get this code off someone else?

Please use code tags. You can find info on them in the FAQ.

got this from the book..just kind of having trouble with classes and such..srry

Create an instance of that class, set it a radius and then print it:

Code:

---

int main(){
    Circle c;
    c.setRadio(34);
    cout<<c.getArea();
}

---

But, ideally, if you've gotten this far, the book should really have explained how to do what you're asking to do. Can I ask what the book is?
