Question

For this lab you must write a complete class in C++. This will be a class named BankAccount. This class must have the following private variables:

1. accountHolderName : string

2. balance : double

3. interestRate: double

This class must have the following public constructor:

1. BancAccount(name : string, balance : double, rate : double)

This class must have the following public member functions:

1. getAccountHolderName() : string a. returns the account holders name

2. getBalance() : double a. returns the current balance

3. getInterestRate() : double a. returns the current interest rate

4. deposit(amount : double) : void a. adds the amount to the balance

5. withdraw(amount : double) : void a. subtracts the amount from the balance

6. applyInterest() : void a. adds interest (balance * interestRate) to the balance

You must write the complete and correct BankAccount.h file that will contain the class declaration.

You must write the complete and correct BankAccount.cpp file that will contain the implementation code.

Explanation / Answer

bankaccount.h

#ifndef BANKACCOUNT_H
#define BANKACCOUNT_H
#include <string>

class BankAccount {
private:
   std::string accountHolderName ;
   double balance;
   double interestRate; // in dollars
public:
   BankAccount(std::string name, double balance, double rate);
   std::string getAccountHolderName();
   double getBalance();
   double getInterestRate();
   void deposit(double amount);
   void withdraw(double amount);

} ;

#endif

BankAccount.cpp

#include "bankaccount.h"
#include<iostream>
#include <string.h>
using namespace std;
double balance;
double interestRate;

BankAccount::BankAccount(std::string initaccountHolderName, double initbalance,
double initrate) {
balance = initbalance;
accountHolderName = initaccountHolderName;
interestRate = initrate;
}

double BankAccount::getBalance () {
return balance;
}

string BankAccount::getAccountHolderName () {
return accountHolderName;
}

void BankAccount::deposit (double amount) {
balance += amount;
}

double BankAccount::getInterestRate () {
return interestRate;
}

void BankAccount::withdraw (double amount) {
if (balance < amount)
cerr << "Insufficient funds ";
else
balance -= amount;
}

void applyInterest(){
balance = balance + balance*interestRate;
}
