Chapter 4, Problem 9PP
Define a class whose objects are records on animal species. The class should have instance variables for the species name, population, and growth rate. The growth rate is a percentage that can be positive or negative and can exceed 100%. Include a suitable collection of constructors, mutator methods, and accessor methods. Include a toString method and an equals method. Include a boolean valued method named endangered that returns true when the growth rate is negative and returns false otherwise. Write a test

Create a Class Pet with the following data members
Identification: String
species : String (e.g. cat, dog, fish etc)
breed: String
Age (in days): int
Weight: float
Dead: boolean
1. Provide a constructor with parameters for all instance variables.
2. Provide getters for all and setters for only breed, and weight
3. Provide a method growOld() that increases the age of the pet by one day. A dead pet wont grow old
4. Provide a method growHealthy(float w) that increases the weight of the pet by the given amount w. A dead pet cannot grow healthy.
5. Provide a method fallSick(float w) that reduces the weight of the pet by the given amount. The least weight a pet can have is 0 which will mean that the pet has died. If the value of weigh is 10 kg and the method is called with an argument of 11 kg then you will set it to 0 and set the dead to an appropriate value to mark the death of the pet
6. Provide a toString method that shows an appropriate well formatted string…
PYTHON:
Define the Artist class with a constructor to initialize an artist's information and a print_info() method. The constructor should by default initialize the artist's name to "None" and the years of birth and death to 0. print_info() should display Artist Name, born XXXX if the year of death is -1 or Artist Name (XXXX-YYYY) otherwise.
Define the Artwork class with a constructor to initialize an artwork's information and a print_info() method. The constructor should by default initialize the title to "None", the year created to 0, and the artist to use the Artist default constructor parameter values.
Ex: If the input is:
Pablo Picasso 1881 1973 Three Musicians 1921
the output is:
Artist: Pablo Picasso (1881-1973) Title: Three Musicians, 1921
If the input is:
Brice Marden 1938 -1 Distant Muses 2000
the output is:
Artist: Brice Marden, born 1938 Title: Distant Muses, 2000

A StepTracker object is created with a parameter that defines the minimum number of steps that must be taken for a day to be considered active. The StepTracker class provides a constructor and the following methods. addDailySteps, which accumulates information about steps, in readings taken once per day activeDays, which returns the number of active days averageSteps, which returns the average number of steps per day, calculated by dividing the total number of steps taken by the number of days tracked The following table contains a sample code execution sequence and the corresponding results.

If the argument object holds the same data (i.e. length and width) as the calling object, this method should return true. Otherwise, it should return false. a toString method (that returns a String representation of the tract’s length, width, and area). Demonstrate the class in a program by creating an array of three LandTract objects initialized with user input. Then, print the info of the LandTract objects stored in the array by invoking the toString method (implicitly or explicity). Also, use the equals method to compare at least two LandTract objects and print wether they are of equal size or not. Sample Output:…arrow_forward

- Objective: At the end of the activity, the students should be able to: Apply method overloading in a program. Procedure: 1. Develop a simple program for an individual savings account. Create two (2) classes named AmountDue (no class modifier) and RunAmountDue (public). 2. For the AmountDue class, create three (3) overloaded methods named computeAmountDue based on the following conditions: With a single parameter: It represents the price of one (1) item ordered. Add 12% tax and return the total due. With two (2) parameters: These represent the price of an item and the quantity ordered. Multiply the two (2) values, add 12% tax, and return the total due. With three (3) parameters: These represent the price of an item, the quantity ordered, and the discount amount. Multiply the quantity and price, deduct the discount amount, add 12% tax, and return the total due. 3.

All of the new books need to be cataloged and sorted back on the shelf. You don’t need to keep track of what customer has the book or not, just whether they are checked in or out. Objects You need to create a class called LibraryBook. It needs to have the following member variables, stored privately: string title, string author, and string ISBN. You also need to have a Boolean to store its status whether it’s checked out or not. Call this variable checkedOut. Create a header file and a .cpp file for the LibraryBook class. Call it LibraryBook.cpp and LibraryBook.h For functions, this library book class needs to have: A default constructor setting all strings blank and the checked out status to false A constructor setting all strings through the parameters (title, author, ISBN), and setting the checked out status to false. “Getters” to get the values from the…arrow_forwardCreate an automobile class that will be used by a dealership as a vehicle inventory program.

All methods should include try..catch constructs. Except as noted all methods should return a success or failure message (failure message defined in "catch"). Create an additional class to call your automobile class (e.g., Main or AutomobileInventory). Include a try..catch construct and print it to the console. Call automobile class with parameterized constructor (e.g., "make, model, color, year, mileage"). Then call the method to list the values.
