Help on code!

[Grigor92]

Im supposed to create an to array of eight Circle objects initialized with the radii which is in the program. Also I must use bubble sort to arrange the objects is ascending order. Please help!

ERRORS:
'initializing' : cannot convert from 'double' to 'Circle'
'setRadius' : is not a member of 'Circle'
see declaration of 'Circle'
'findArea' : is not a member of 'Circle'
see declaration of 'Circle

#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

class Circle
{
public:
Circle();
};

//Function prototype
void bubbleSort( Circle array[], int);

const int NUM_CIRCLES = 8;

int main()
{ 
Circle circle[NUM_CIRCLES] = {2.5, 4.0, 1.0, 3.0, 6.0, 5.5, 3.5, 2.0 };

for (int index = 0; index < NUM_CIRCLES; index++)
{
double r;
cout <<"The radius for circle" << (index+1) << ": ";
circle[index].setRadius(r);
}


cout << fixed << showpoint << setprecision(2);
cout <<"\nHere are the area of the " << NUM_CIRCLES
 << " cricles.\n";
for (int index = 0; index < NUM_CIRCLES; index++)
{
cout << "circle " << (index+1) << setw(8)
 << circle[index].findArea() << endl;
}

return 0;
}

The error are pretty self-explanatory. You didn't define any members for Circle other than the constructor, which you made take no parameters, forbidding the kind of initialization you used on line 19.
