Question

Write a Savings Account class that stores a savings account's
annual interest rate and balance The class constructor should accept
the amount of the savings account's starting balance. The class
should also have methods for subtracting the amount of a withdrawl,
adding the amount of a deposite, and adding the amount of monthly
interest to the balance. The monthly interest rate is the annual
interest rate divided by 12. To add the monthly interest to the balance,
multiply the monthly interest rate by the balance and add the result to
the balance

Explanation / Answer

Dear, Here is the code Haven't specified the language you are looking for giving you in c++ please come back Class:

//          Class Date definition

class SavingsAccount

{

public :

                        SavingsAccount();      //          default constructor

                       

                        //          set the balance amount

                        void setSavingsBalance( double );

                       

                        //          returns the balance

                        double getSavingsBalance();

                       

                        //          calculates the monthly interest

                        void calculateMonthlyInterest();

                       

                        //          modifies the rate of interest

                        //          static member function

                        static void modifyInterestRate( float );

                       

            //          ~SavingsAccount();    //          destructor

                       

private :

            static float annualInterestRate;                      

            double savingsBalance;

 

};         //          end class SavingsAccount        Main code:  

int main() //   function main begins program execution

{

     //   instantiate two different objects of
         //type SavingsAccount

     SavingsAccount account1, account 2;  

    //   print the initial balances of the objects

  cout << " Initially saver1's account has a balance of $ "

<< account 1.getSavingsBalance();

  cout << " Initially saver2's account has a balance of $ "

<< account 2.getSavingsBalance();

    

     //   set the balances to be 2000 and 3000

     account1.setSavingsBalance(2000.00);

     account2.setSavingsBalance(3000.00);

 // print the balances of the objects after setting
 //the balances

     cout << " The saver1's account has a balance of $ "

<< account1.getSavingsBalance();

     cout << " The saver2's account has a balance of $ "

<< account2.getSavingsBalance();

    

     //   modify the rate of interest to 3

     account1.modifyInterestRate(3);

     account2.modifyInterestRate(3);

    

     //   calculate the interest amounts

     account1.calculateMonthlyInterest();

     account2.calculateMonthlyInterest();

    

     //   print the balances after the interest was added

     cout<<" The saver1's account after an annualInterest
     of 3% has a balance of $"<< account1.getSavingsBalance();      cout<<" The saver2's account after an annualInterest
     of 3% has a balance of $"<< account2.getSavingsBalance();

          //   modify the rate of interest to 3

     account1.modifyInterestRate(4);

     account2.modifyInterestRate(4);

    

     //   calculate the interest amounts

     account1.calculateMonthlyInterest();

     account2.calculateMonthlyInterest();

    //   print the balances after the interest was added

     cout<<" The saver1's account after an annualInterest of 4% has a balance of $"  

                                      << account1.getSavingsBalance();

     cout<<" The saver2's account after an annualInterest of 4% has a balance of $"

                                                                          << account2.getSavingsBalance();

    

     return 0; // indicate program executed successfully

}
