Chapter 9, Problem 9.7PE
(The Account class) Design a class named Account that contains:
- A private int data field named id for the account (default 0).
- A private double data field named balance for the account (default 0).
- A private double data field named annual InterestRate that stores the current interest rate (default 0). Assume that all accounts have the same interest rate.
- A private Date data field named dateCreated that stores the date when the account was created.
- A no-arg constructor that creates a default account.
- A constructor that creates an account with the specified id and initial balance.
- The accessor and mutator methods for id, balance, and annual InterestRate.
- The accessor method for dateCreated.
- A method named getMonthlyInterestRate () that returns the monthly interest rate.
- A method named getMonthlyInterest () that returns the monthly interest.
- A method named withdraw that withdraws a specified amount from the account.
- A method named deposit that deposits a specified amount to the account.
Draw the UML diagram for the class then implement the class. (Hint: The method getMonthlyInterest () is to return monthly interest, not the i nterest rate.
Monthly interest is balance * monthlyInterestRate. monthlyInterestRate is annual InterestRate /12. Note annual InterestRate is a percentage, for example 4.5%. You need to divide it by 100.)

Bank Accounts (Use Python)
Write a program that accepts bank transactions and prints out the balance of an account afterwards.
PROGRAM DESIGN
Create a class named bankAccount. A bank account should have the following attributes: accNumber, balance, and dateOpened. This class should also have the option to do the following transactions: deposit, withdraw and drop. Initially there is only one bankAccount active in the program, with a balance amount of 1515, and was opened back in 10/01/1987.
Depositing adds to a current bankAccount’s balance, while withdrawing – does otherwise. Dropping would equate the current balance to zero. Refer to the following class diagram for more details about the current bankAccount:
bankAccountaccNumber = 1balance = 1515dateOpened = "10/27/1987"
deposit(dep)withdraw(wd)drop(accNumber)
INPUTThe input would be a string that contains the following data: the transaction to be done (dep – for deposit, wd – for withdraw and drop – for drop), the accNumber, and…
5 (The Time class) Design a class named Time. The class contains:
■ Data fields hour, minute, and second that represent a time.
■ A no-arg constructor that creates a Time object for the current time.
■ A constructor that constructs a Time object with a specified elapse time since
the middle of night, Jan 1, 1970, in seconds.
■ A constructor that constructs a Time object with the specified hour, minute, and
second.
■ Three get functions for the data fields hour, minute, and second.
■ A function named setTime(int elapseTime) that sets a new time for the
object using the elapsed time.
Draw the UML diagram for the class. Implement the class. Write a test program
that creates two Time objects, one using a no-arg constructor and the other using
Time (555550), and display their hour, minute, and second.
(Hint: The first two constructors will extract hour, minute, and second from the
elapse time. For example, if the elapse time is 555550 seconds, the hour is 10,
the minute is 19, and the…

- Nutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0 where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…arrow_forward1. (The Fan class) Design a class named Fan to represent a fan. The class contains: The Fan class Three constants named SLOW, MEDIUM, and FAST with the values 1, 2, and 3 to denote the fan speed. A private int data field named speed that specifies the speed of the fan (the default is SLOW). A private boolean data field named on that specifies whether the fan is on (the default is false). A private double data field named radius that specifies the radius of the fan (the default is 5). A string data field named color that specifies the color of the fan (the default is blue). Accessor and mutator methods for all four data fields. A no-arg Constructor that creates a default Fan.

This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its…arrow_forward
