This is the HW guide:

A Classy Account

We will use classes to represent bank accounts and money respectively, and write functions that allow us to interact with our accounts. Requirements:

You will write your code where prompted to do so, and the main() and testing functions are not to be altered Create two classes and name their types Account and Money Use initialization sections where possible for all constructors With the sole exceptions being the print() functions, no other functions should be printing to the screen unless an error message must be displayed Money Class Requirements Negative amounts of Money shall be stored by making both the dollars and cents negative The Money class shall have 4 constructors * A default constructor that initializes your Money object to $0.00 * A constructor that takes two integers, the first for the dollars and the second for the cents * A constructor that takes one integer, for a dollar amount and no cents * A constructor that takes one double, and can assign dollars and cents accordingly bool isNegative() const * Returns true if your amount of money is negative void add(const Money &m) * The sum shall be stored in the calling object void subtract(const Money &m) * The difference shall be stored in the calling object bool isEqual(const Money &m) const void print() const * This function prints the amount of Money you have; it must print a $, and always show two decimal places * Negative amounts of Money shall be represented in the following manner: ($X.XX) The Money class shall have two private data members AND one helper function * An integer that represents how many dollars you have. * An integer that represents how many cents you have. 1 * A function getPennies() that returns the equivalent amount of pennies for the calling object Account Class Requirements The Account class shall have 4 constructors * A default constructor that initializes your Account object with a name Savings, an interest rate of 0.00%, and an initial balance of $0.00 * A constructor that takes a string, double, and Money object to initialize your Accounts name, interest rate, and balance respectively * A constructor that takes a string, double, and an integer that represents your initial balance (a clean dollar amount) * A constructor that takes a string, double, and a double that represents your initial balance std::string getName() const double getRate() const const Money getBalance() const void setName(std::string newName) void deposit(const Money &m) void deposit(int d, int c) void deposit(int d) void deposit(double d) * For all versions of the deposit function, the function shall not accept negative amounts of money * For all versions of the deposit function, the balance of the account shall be updated accordingly const Money withdraw(const Money &m) const Money withdraw(int d, int c) const Money withdraw(int d) const Money withdraw(double d) * For all versions of the withdraw function, the function shall not accept negative amounts of money * For all versions of the withdraw function, the user shall not overdraw by more than $50.00 * For all versions of the withdraw function, the balance of the account shall be updated accordingly void accrue() * The accrued interest shall be calculated and added to the balance void print() const * This function shall only print the balance; formatting requirements are identical to that of the Money class * This function prints the amount of Money you have; it must print a $, and always show two decimal places * Negative amounts of Money shall be represented in the following manner: ($X.XX) 2 void transferTo(Account &dest, const Money &amount) * The function shall not transfer negative amounts of money * The balances of both accounts shall be updated accordingly The Account class shall have 3 private data members * A Money object that will represent how much money is in the account * A double to represent the interest rate as a decimal value * A string object to represent the name of the account. (Checking, Savings, CD, etc.) Define the following non-member function: const Account createAccount(); There are minor changes to this function over the previous assignment It will prompt the user for the account name, interest rate, and starting balance in that order The prompts shall appear as follows: Let's set up your account. First, what's the name of the account? What is the interest rate of your [NAME] account? Finally, what is the starting balance of your [NAME] account? You may NOT assume that the name of the account contains only a single word You may assume the user will always type an interest rate as a decimal value (e.g. 0.05) The user is allowed to type their amount of money with or without a $ A sample run of your program shall look like this: $ ./hw02 < inputs *** TESTING MONEY CLASS FUNCTIONS *** 3.

Finally, what is the starting balance of your Roth IRA account? *** TESTING NON-CLASS FUNCTION CREATEACCOUNT *** 1. Account Name:...Mutual Fund 2. Interest Rate:..0.05 3. Balance:........$2500.00 $ Hints: For the overloaded deposit and withdraw functions, you do not need to re-write the function bodies multiple times The hints from the previous homework also apply here and are repeated You are free to write any extra helper functions that might make your life easier The functions listed in the Requirements are required (shocker!), but you may find it useful to write other helper functions Converting a double to a Money object can cause rounding errors * You may want to look up the round() function Converting an amount of money to an equivalent amount of pennies makes a lot of logical work go away You can create a file that holds user inputs and use it to streamline your testing. http://linuxcommand.org/lc3_lts0070.php Reminders: Be sure to include a comment block at the top of the file with the required information Refer to the General Homework Requirements handout on Blackboard Provide meaningful comments If you think a comment is redundant, it probably is If you think a comment is helpful, it probably is Remember that you are writing comments for other programmers, not people who know nothing (obligatory Jon Snow) about coding There will be no extensions 4
