Please answer this c++ static question!?

This program won't compile correctly

// Bell.h file

#ifndef BELL_H

#define BELL_H

class Bell

{

private:

int count1;

static int count2;

public:

Bell()

{ count1 = 0; }

void ring(int);

int getCount() const

{ return count1; }

static int getStaticCount() const

{ return count2; }

};

#endif

//specification of ring function and main function (Bell.cpp)

#include <iostream>

#include "Bell.h"

using namespace std;

void Bell::ring(int num_rings)

{

for (int index = 0; index < num_rings; index++)

{

cout << "ring ";

count1++;

count2++;

}

}

int main()

{

const int NUM_RINGS1 = 3, NUM_RINGS2 = 4;

Bell bell1, bell2;

bell1.ring(NUM_RINGS1);

bell2.ring(NUM_RINGS2);

cout << "Count for first bell: " << bell1.getCount();

cout << "Count for second bell: " << bell2.getCount();

cout << "Static Counter: " << bell1.getStaticCount();

system("pause");

return 0;

}

Basically bell1 should ring 3 times and bell2 should ring 4 times

and should print out the count for each bell and the static counter,

which is the same for both.

Please help me? I'm not so good with programming
