In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.

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. 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 print_info() # TODO: Create dog pet (using dog_name, dog_age, dog_breed) and then call print_info() # TODO: Use my_dog.breed to output the breed of the dog
Consider the following class code segment: class aNewClass { public: ……. private: string name; int *q; int length; }; // constructor aNewClass::aNewClass() { q = new int[10]; // dynamic data …. } Name at least ONE thing you should add/code for the dynamic data in this class. (HINT: Look at the member variables).
Write a program which has a class named binary which has a character array to store a binary string. The class decimal derives from class binary and contains an integer data member. Another class called octal also derives from binary. Each class should contain constructors and appropriate data members to input and display the elements. The display function of binary class displays the binary equivalent, octal class’s display function displays octal equivalent whereas decimal class’s display function displays the decimal equivalent (question is a part of c++)

Create a class called Pizza (Pizza.java). It should have the following private data members: String size: size of the pizza could be small, medium, or large int numOfToppings: number of toppings could be 1, 2 or 3. double price and should provide the following methods: default constructor (set size to an empty string, numOfTopping and price to 0) non-default constructor Pizza(String s, int n, double p) getters and setters for the three data members method toString()returns a string representing the Pizza object, formatted as: Size: large Toppings: 2 Price: 9.95 method equals (Object obj) to indicate some other object is “equal to” this one public class Pizza { }

Write a Rational class. Recall a rational number is a rational number, composed of two integers with division indicated. The division is not carried out, it is only indicated, as in 1/2, 2/3, 15/32. You should represent rational numbers using two int values, numerator and denominator. #include <iostream> #include <string> #include <stdlib.h> using namespace std; class rational { public: /* default constructor set the rational number to 0, (i.e., numerator is 0, denominator is 1) */ rational(); /* Set the invoking object's value from user input */ void input(); /* Display invoking object's value in the standard output, in the form of numerator/denominator */ void output() const; //return the invoking object's numerator int get_numerator() const; //return the invoking object's denominator int get_denominator() const; // Set invoking object to be the sum of op1 and op2 void Add(const rational& op1, const rational& op2); // Set the invoking…
