Question

Im having trouble with this C++ program. Lab 10/object/test files provided

// An Account Class has been created. // Based on the Savings.cpp program on page 42 of Ch09PPT(lab10) using this Account object to get the same output. Modify AccountTest.cpp with your forloop and object function call // submityour source code and output in PDF format Output example below: Savings Account Deposit: 1eee Rate (in decimal form): e.e2 Year 1: $1020.ee Year 2: $1040.40 Year 3: $1061.21 Press any key to continue . .._ 5

// Encapsulation: A class encapsulates all of an object’s attributes and

behaviors.

// Inheritance: The relationship between a superclass and an inherited

class is called an “is a” relationship.

// Abstraction: An abstract class cannot be instantiated, but other

classes are derived from it (information hiding).

// Polymorphism: means the ability to take many forms. e.g. Account acct

= new CheckingAccount();

Please find the code below::

Account.h

#ifndef ACCOUNT_H_
#define ACCOUNT_H_
#ifndef Account_Header

#include <iostream>

#include <cmath>

using namespace std;

class Account { //class header

private:

   double acctBalance_=0.0; //data member

   double interestRate_=0.0;

public:

   Account() {} //default constructor

   Account(double interestRate) {

       interestRate_=interestRate;

   }

   double checkBalance() { //getter

       return acctBalance_;

   }

   double getRate() {

       return interestRate_;

   }

   double getBalance(int year) {

       double balance = 0.0;

       balance = acctBalance_ * pow((1+interestRate_), year);

       return balance;

   }

   void addBalance(double deposit) { //setter

       acctBalance_ += deposit;

   }

   void setBalance(double balance) {

       acctBalance_ = balance;

   }

   void setRate(double interestRate) {

       interestRate_ = interestRate;

   }

};

#endif

#endif /* ACCOUNT_H_ */

main.cpp

#include <iostream>
#include "Account.h"
#include <iomanip>
using namespace std;
int main() {
   cout << fixed << showpoint << setprecision(2);
   Account acct = Account();
   acct.setRate(0.02);
   acct.addBalance(1000);
   cout << "Current Balance: $" << acct.checkBalance() << endl;
   cout << "Rate (in decimal form ) : " << acct.getRate() << endl;
   // add your for loop with function call here
   for(int i=1;i<=3;i++){
       cout<<"Year "<<i<<" : $"<<acct.getBalance(i)<<endl;
   }
   return 0;
}

output:
