CLasses

Please im just practicing to get better at classes:

Code:

---

#include<iostream.h>
#define PI 3.14

class circle {
int x;

public:
int radiuss (int r) {x=r;}
int radius (void) {return  PI(x^2);}
};

int main (){
circle one;
one.radiuss (2);
cout<<one.radius;
return 0;
}

---

So what is your question? I assume you will have a problem with x^2 since the "^" operator is actually the XOR operator...

Give your member variables and functions more descriptive names.

Code:

---

class circle
{
private:
        int nRadius;
public:
        void SetRadius (int nRadius_) {nRadius=nRadius_; }
        int GetArea (void) {return  PI*pow(nRadius,2); }
};
