For this assignment you will be building on the Fraction class you began last week. All the requirements from that class are still in force. You'll be making five major changes to the class. Delete your set() function. Add two constructors, a default constructor (a constructor that takes no parameters) and a parameterized constructor (a constructor that takes parameters). The default constructor assigns the value 0 to the Fraction. In the parameterized constructor, the first parameter will represent the initial numerator of the Fraction, and the second parameter will represent the initial denominator of the Fraction. Since Fractions cannot have denominators of 0, the default constructor should assign 0 to the numerator and 1 to the denominator. Also, the parameterized constructor should check to make sure that the second parameter is not a 0 by using the statement "assert(denominatorParameter != 0);". To use the assert() function you'll also need to #include <cassert>. (Note, I…
I've gotten stuck on this practice problem. I need help figuring this out. You need to make a Pet class that holds the following information as private data members: the name of the pet (e.g. "Spot", "Fluffy", or any word a user enters) the type of pet (e.g. dog, cat, snake, hamster, or any word a user enters) level of hungriness of the pet (2 means hungry, 1 means content, 0 means full) Your class also needs to have the following functions: a default constructor that sets the pet to be a dog named Buddy, with level of hungriness being “content” a parameterized constructor to allow having any type of pet the order of the parameters is: name of the pet, type of pet, hungriness level a PrintInfo function that prints the info for the pet according to the sample output below a TimePasses function that increases the hungry level of the pet by one (unless its hungry level is already 2, meaning hungry). a FeedPet function that changes the hungry level of the pet to 0 (Full) You must…

!! E! 4 2 You are in process of writing a class definition for the class Book. It has three data attributes: book title, book author, and book publisher. The data attributes should be private. In Python, write an initializer method that will be part of your class definition. The attributes will be initialized with parameters that are passed to the method from the main program. Note: You do not need to write the entire class definition, only the initializer method lili lilı
