Question

Thanks :))))))))))))

Account Class class Account {public: Account(double initBal=0);//balance must be non-negative//cout "attempt at negative balance"//on illegal initialization bool credit(double amt);//add amt to balance//amt must be non-negative//cout "attempt at negative deposit"//on illegal transaction bool debit(double amt);//subtract amt from balance//amt must be non-negative//cout "attempt at negative withdrawl"//balance must be non-negative//if attempt to overdraw cout//"debit amount exceeds balance"//leave balance unchanged//returns false if debit rejected double getBalance();//return current balance private: double balance;}; Savings Class class Savings: public Account {public: Savings (double initBal, double intRate); void yearlyUpdate();//update the balance double calcInterest(); private: double interestRate;//a percent 4 means 4%}; Checking Class class Checking: public Account {public: Checking(double initBal, double fee); bool credit(double amt); bool debit(double amt); private: double transFee;//fee for successful//credit or debit operation}; In addition to providing implementation (.cpp) files for the aforementioned classes, you must also provide a main function that exercises the Checking and Savings classes. Make sure to include usage of the inherited methods from the Account base class So, you should have the following implemented to turn in: main.cpp Account.cpp

#include<iostream>

using namespace std;
