Hi i have to create a SavingsAccount class. Use a static data members to contain the annualIntrestRate for each of the server. each member of class contains a private data member savingBalance includin the amount the saver currently has on deposit. provide a calculateMonthlyIntrest member function that calculates the monthly intrest by multiplying the balance by annualIntrestRate divided bye 12; this intrest should be added to savingBalance. provide a static data member function modifyIntrestRate that sets the static annualIntrestRate to a new value. write a driver program to test class SavingsAccounts. Instantiate two diffrent savingBalance objects, saver1 and saver2, with balance of $2000.00 and $3000.00, respectively. set annualIntrestRate to 3%, then calculate the monthly intrest and print the new balance for each of the saver. then set the annualIntrestRate to 4% and calculate the new month intrest and print the new balances for each of the saver.

here is so for what i got all i need is to help me what should i put in main
this is the header file

Code:
//HEADER FILE OF SAVING ACCOUNTS

#ifndef SAVINGACCOUNT_H
#define SAVINGACCOUNT_H

class SavingsAccount
{
public:
	//	static void modifyInterestrate(float interest);
	SavingsAccount(float);
	~SavingsAccount();
	float calculateMonthlIntrest();
	float getSavingBalance()const;
	static void modifyInterestrate(float);
private:
	float savingBalance;
	static float annualInterstRate;
};

#endif 
this is the savingAccount.cpp
#include <iostream.h>
#include "SavingAccount.h"

float SavingsAccount::annualInterstRate =0.0;

SavingsAccount::SavingsAccount(float balance)
{
	savingBalance = balance;

}
SavingsAccount::~SavingsAccount()
{
	cout<<"Destructor"<<endl;
}
float SavingsAccount::calculateMonthlIntrest()
{
	return savingBalance * annualInterstRate / 12.0f;
}
float SavingsAccount::getSavingBalance()const
{
	return savingBalance;
}
void SavingsAccount::modifyInterestrate(float interest)
{
	annualInterstRate = interest;
}
and In main i need help what should i put 
int main()

SavingsAccount saver1, saver2 
// what comes up next  in main
