The Square class inherits from the Shape base class. The Square class overrides the get_area() function. What is wrong with the following definition of get_area in the Square class? double Square::get_area() const { } double base_area = get_area(); return base_area + bonus; The Square class cannot call the get_area () function in the base class The initialization of base_area should have been double base_area = Shape:: area The call to get_area should be written as this->get_area() The call to get_area should be written as Shape::get_area()

dayType Class We will be working on a project that designs a class calendarType, so that a client program can use this class to print a calendar for any month starting Jan 1. 1900. An example of the calendar for September 2019 is: September 2019 Sun Mon Tue Wed Thu Fri Sat 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 We will develop several classes which will work together to create a calendar. The first of these classes is called dayType which will manipulate a day of the week. The class dayType will store a day, such as Sun for Sunday. The class should be able to perform the following operations on an object of type dayType: a. Set the day. b. Print the day. c. Return the day. d. Return the next day. e.…

Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…
Write a Rectangle class that has the following fields: Length (L): a double Width (W): a double The class should have the following functions: Constructor: accepts the length (L) and the width (W) of a rectangle as arguments. Constructor: does not take any parameters and initializes the length(L) and width(W) to zero. A function called getArea which returns the area of the rectangle. A function called getPerimeter which returns the perimeter of the rectangle. {note: The area of a rectangle = L*W, and its perimeter = 2*(L+W) } Then, write a program to ask the user to enter the length and width of a rectangle, and then use the above class to calculate and print the area and perimeter of the rectangle.
The base class Pet has attributes name and age. The derived class Dog inherits attributes from the base class Pet class and includes a breed attribute. Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute. Ex: If the input is: Dobby 2 Kreacher 3 German Schnauzer the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer Here is the original code: class Pet:def __init__(self):self.name = ''self.age = 0 def print_info(self):print('Pet Information:')print(' Name:', self.name)print(' Age:', self.age) class Dog(Pet):def __init__(self):Pet.__init__(self)self.breed = '' my_pet = Pet()my_dog = Dog() pet_name = input()pet_age = int(input())dog_name = input()dog_age = int(input())dog_breed = input() # TODO: Create generic pet (using pet_name, pet_age) and then call…

Novice: How can i access a main class objects from outside the function? / Better Alternative? If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.
Implement the following class MyPhoneBook. You can add additional private member variables and functions.The class has the following private member variables:1- names and phones: Dynamic arrays of strings.2- phoneBookSize: An int that holds size of phonebook.The Class has the following public member functions:1- Parametrized Constructor that takes the size of PhoneBook and allocate dynamic arrays of names and phones and a copy constructor to initialize a PhoneBook using another PhoneBook.2- A function addEntry that adds a name and phone number at the first empty space at corresponding arrays, and returns true if entry is added, false otherwise. An entry is added if there’s space in the array and if phone number if valid. It checks for the validity of the phone number by ensuring that it has 11 digits, and doesn’t include any alphabets or special characters.3- A function displayEntryAtIndex(int) that displays a name and phone number at the specified index. It returns true if the index…
