這才是我寫的|||

#include <iostream>
using std::cout;
using std::cin;
using std::ios;

class SavingsAccount{
public:
        SavingsAccount(double, double);
        void modifyInterest(double);
        void CalculateMRate(double);
        void result();
private:
        static double annualInterestRate;
        double SavingBalance;
};


double SavingsAccount::annualInterestRate=0;

SavingsAccount::SavingsAccount(double AR, double SB)
        {SavingBalance=SB;}

void SavingsAccount::modifyInterest(double newrate)
        {annualInterestRate= newrate;}

void SavingsAccount::CalculateMRate(double AR){
        double Mrate= (AR/12) ;
        double Minterest= SavingBalance*Mrate;
        SavingBalance= SavingBalance+Minterest;
        }

void SavingsAccount::result(){
        CalculateMRate(annualInterestRate);
        cout<<"The Savings Balance after a month is  ";
        cout<< SavingBalance <<"\n";
        }

        cout<<"Savings Balance of saver1=2000,\n";
        cout<<"Savings Balance of saver2=3000\n\n";

        cout<<"The original Annual interest rate is 3%:\n";
        saver1.modifyInterest (0.03);
        saver2.modifyInterest (0.03);
        cout<<"saver1:";
        saver1.result();
        cout<<"saver2:";
        saver2.result();

        cout<<"\nSet the Annual interest rate to 5%:\n";
        saver1.modifyInterest (0.05);

        cout<<"saver1:";
        saver1.result();

寫完覺得好簡單喔
之前怎麼那麼笨|||
