Question
Class Account
Private Data Members:
static int genId
int accountId
double balance
double annualInterestRate
Static data member used to assign value to accountId;
Account ID
Current Balance of the account
Current Annual Interest Rate of the Account (ex. 4.5)
Public Member Functions:
Account()
Account(int id, double bal, double interest)
Constructors:
Default Constructor (no parameters)
Overloaded Constructor: Three-Parameter Constructor
Public Member Functions:
void setAccountId (int x)
void setBalance(double x)
void setInterest(double x)
Setters:
Function sets id to x
Function sets balance to x
Function sets annualInterestRate to x
Public Member Functions:
int getAccountId()
double getBalance()
double getInterest()
static double getGenId()
Getters:
Function returns accountId
Function returns balance
Function returns annualInterestRate
Static Function used to returns genId
Public Member Functions:
double getMonthlyInterestRate()
Function calculates the monthly interest rate and returns the value
double getMonthlyInterest()
Function calculates the amount earned per month from interest and returns the value rounded to 2 decimal places. (Assume interest is not compounding)
Bool withdraw(double amount)
Function only allows withdraw if the current balance is greater than or equal to the withdraw amount. Return true if withdrawal is successful, else return false.
void deposit(double amount)
Function adds the amount passed as a parameter to the current balance.
Write a program that creates an array of 10 Account objects. (IN C++)
When creating each Account object, make sure the object is initialized in both the default and overloaded constructor functions with following guidelines:
Each object’s accountId should be the index of its position within the array. Add a static data member to initialize the accountId.
The balance of each Account object should be created from a random number generator function returning values between 100.00 and 200.00.
The interest rate of each Account object should be created from a random number generator function returning values between 1.5 and 5.0. This return value should be rounded to one decimal place.
Main Program and remaining member function defintions:
The program should then ask the user to select an account number from 0 – 9 or -1 to exit the program.
If an account number is selected, then the user should be presented with the following options:
Enter 1 to make a deposit
Ask the user for the amount they wish to deposit
Enter 2 to make a withdraw
Ask the user for the amount they wish to withdraw
Return if withdrawal was successful or unsuccessful depending on function return value
Enter 3 to check balance
Display the account’s current balance
Enter 4 to check interest rate
Display the account’s monthly and yearly interest rate
Enter 5 to display account summary
Display account id, balance, monthly interest rate, and monthly interest amount
Enter 99 to exit to the main menu to select another account number.
