- build a student class implement the student class with the following instance variables: * id * firstName *lastName *dateOfBirth * Major create an __init__ function adn initialize all the fields make the "major" an option field and set a default value to "undefined" create a setter and getter function for all these five variables create another function: "print_student_info()" which prints 5 pieces of information: id, first name, last name, date of birth, and major. Make sure to have proper formatting done for printing these 5 things. Use the student class Task 1: create an empty list named "all_students" Task 2: create a variable named "id" and initialize it to 100 (some default value to start with, next id would be 101) Task 3: ask the user for input "How many students:" Task 4: Now run a for loop based on that input number and do the following things for each iteration: - get input of student's first name, last name, date of birth, and major - user should be able to skip the…User-defined Class: You will design and implement your own data class. The class will store data that has been read as user input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named MoneyChange. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 6 instance variables to represent amounts for each of the 6 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide a legitimate justification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriate get and set methods for…User-defined Class:You will design and implement your own data class.

- In a population, the birth rate and death rate are calculated as follows:Birth Rate = Number of Births ÷ Population Death Rate = Number of Deaths ÷ PopulationFor example, in a population of 100,000 that has 8,000 births and 6,000 deaths 2per year,Birth Rate = 8,000 ÷ 100,000 = 0.08 Death Rate = 6,000 ÷ 100,000 = 0.06Design a Population class that stores a current population, annual number of births, and annual number of deaths for some geographic area. The class should allow these three values to be set in either of two ways: by passing arguments to a three-parameter constructor when a new Population object is created or by calling the set_population, set_births, and set_deaths class member functions. The class should also have get_birth_rate and get_death_rate functions that compute and return the birth and death rates. Write a short program that uses the Population class and illustrates its capabilities.Input Validation: If a population figure less than 2 is passed to the class, use…#Python IDLE: #Below is my Pizza class ,how would I write the function described in the attached image,based on this class? # The Pizza class should have two attributes(data items): class Pizza: # The Pizza class should have the following methods/operators): # __init__ - # constructs a Pizza of a given size (defaults to ‘M’) # and with a given set of toppings (defaults to empty set). def __init__(self, size='M', toppings=set()): self.size = size self.toppings = toppings # setSize – set pizza size to one of ‘S’,’M’or ‘L’ def setSize(self, size): self.size = size # getSize – returns size def getSize(self): return self.size # addTopping – adds a topping to the pizza, no duplicates, i.e., adding ‘pepperoni’ twice only adds it once def addTopping(self, topping): self.toppings.add(topping) # removeTopping – removes a topping from the pizza def removeTopping(self, topping):…Assignment:The BankAccount class models an account of a customer.

- Quiz: Module 7: Assignment Clase Use an access specifier to make members of CPlusPlus cannot be accessed from outside the class. class CPlusPlus{ [ Select ] int n; 3; Question 6 2 pts Use an access specifier to make members of CPlusPlus accessible from outside the class. class CPlusPlus { public: int n; }; étv MacBook Air 80 DD F2 F3 F4 F5 F6 F7 F8 F9 F10 %23 24 3 4 7 8 R YIn 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.Using classes, design an online address book to keep track of the names, addresses, phone numbers, and dates of birth of family members, close friends, and certain business associates. Your program should be able to handle a maximum of 500 entries. Define a class addressType that can store a street address, city, state, and ZIP code. Use the appropriate functions to print and store the address. Also, use constructors to automatically initialize the member variables. Define a class extPersonType using the class personType (as defined in Example 10-10, Chapter 10), the class dateType (as designed in this chapters Programming Exercise 2), and the class addressType. Add a member variable to this class to classify the person as a family member, friend, or business associate. Also, add a member variable to store the phone number. Add (or override) the functions to print and store the appropriate information. Use constructors to automatically initialize the member variables. Define the class addressBookType using the previously defined classes. An object of the type addressBookType should be able to process a maximum of 500 entries. The program should perform the following operations: Load the data into the address book from a disk. Sort the address book by last name. Search for a person by last name. Print the address, phone number, and date of birth (if it exists) of a given person. Print the names of the people whose birthdays are in a given month. Print the names of all the people between two last names. Depending on the users request, print the names of all family members, friends, or business associates.
