Language: C++ Create a class named City. Assume that a city has a name, a number of inhabitants, a mayor and an area (in km²). Then create three instances of this class: Bremen, Paris and London. Provide suitable setter and getter methods for each of these properties. The class declaration has to be placed into City.h, the class definition has to be placed into City.cpp and the test program where the instances are created has to be in testcity.cpp. You can set the needed data from the main () function by initialization or read it from the key- board.
Write a class ‘Box’ which has three members height, width and depth; To set values and use these members, write mutator and accessor functions for these members. (Hint: there would be 3 Accessor and 3 Mutator functions).
PROGRAMMING LANGUAGE :C++ QUESTION; You need to store hiring date and date of birth for Managers and Employees. You need to create a Date class for this purpose. Create objects of Date class in Manager and Employee classes to store respective dates. You need to write print function in Manager and Employee classes as well to print all information of Managers and Employees. You need to perform composition to implement this task. Create objects of Manager and Employee classes in main function and call print function for both objects. ______________________________________________________________ note : print the specific part of code in following ... Print Date class here: Print updated Manager class here: Print updated Employee class here: Print main function here:
Description: In a hypothetical class, students take two midterms and an optional final. If a student takes the final and gets in it a better score than the lowest of the two midterm scores, then the lowest midterm score would be replaced by the comprehensive final score. The overall score will then be calculated by averaging the three test scores. If the student does not take the optional final, the overall score is calculated using only the two midterm scores. Students’ exam scores are included in the “Question1” tab in the attached worksheet. Empty data entries for the optional comprehensive final means that the student did not take the optional final. Tasks: Task 1: In Question1_Module, code a function that requires midterm1 score, midterm2 score, and comprehensive final as inputs and calculate the overall score per the description above. Task 2: In Question1_Module, code a Sub that uses the function coded in task 1 to fill column ‘I’ of the worksheet and link this…
Help of what these errors mean. In C# • Create a Class, named Student, to hold properties of Student Last Name, Student First Name, Student ID (9 digits), Course Prefix and Number, and the tests (Test 1, Test 2, Test 3, Test 4). Create appropriate setter and getter accessors, and constructors. Use access modifiers. Example: First Name : Pat Last Name : Smythe Student ID : ABC111333 Course Prefix : CIST Course Name : 2431 Test 1 : 100 Test 2 : 90 Test 3 : 80 Test 4 : 88 • Prompt the user for the Student Last and First Name, Student ID, Course Prefix and Number and the tests. • Include at least one exception handling function. • Use an array to store the 4 test grades. • Use a looping structure to populate the array. • Calculate the numeric average based upon the 4 equally-weighted numeric grades. • Display all the data for each of student using a looping structure. • Display the numeric average for each student. • Create a function that will convert the numeric average to a…

Note : ALL Code Must be in OOP (JAVA) And perform all in ecplis (console base) Scenario:You are hired by a game development company. Your task is to create an RPG hack & slashconsole game. The game will have a movement system that will be based on the x, y, zcoordinate system. You will need to start with creating 3 classes.1. A class that represents a player2. A class that represents an enemy3. An abstract class that contains the movement logic.Step 1:Start by creating the superclass which defines the movement system for both enemy andplayer. The movement system is based on the Coordinate system. Imagine an x, y, z plane,the y coordinate is used to move forward and backward in the virtual plane, x to go left andright, z to go up and down.For example, A player with coordinates x, y, z with values -5, 10, 0 represents a player -5units to the left, 10 units forward, and 0 z units mean on the ground. (0, 0, 0) are the baseunits which means the player or enemy is at the start of the…
In number theory, a value can be categorized as a natural number (a whole number >0, often denoted ℕ), an integer (zero or a positive or negative whole number, including the natural numbers, often denoted ℤ), or a real number (which includes the natural numbers and integers, along with all other positive and negative numbers that are not integers, often denoted ℝ). a) write a definition for a number class that contains: (i) A single field suitable for storing either a natural number, or an integer, or a real number; (ii) Setter and getter methods for manipulating this field; (iii) A constructor that initializes new objects of number to have the value 1 (unity); (iv) a method that determines which kind of number is currently stored (returning 0 if the number is real and an integer and a natural number, 1 if the number is real and integer but not a natural number, and 2 if the number is real but neither an integer nor a natural number) Java code needed
Write in C++ Language (Happy Coding):Create a class named 'Programming'. While creating an object of the class, if nothing is passed to it, then the message "I love programming languages" should be printed. If some String is passed to it, then in place of "programming languages" the name of that String variable should be printed.For example, while creating the object if we pass "cpp", then "I love cpp" should be printed.
use java (ArrayList, inheritance, polymorphism, File I/O and basic Java) Student class: First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information, and all of these should be defined as Private: A first name (given name) A last name (family name/surname) Student number (ID) – an integer number (of type long) The Student class will have at least the following constructors and methods: (i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables of Student. (ii) only necessary set and get methods for a valid class design. (iii) a reportGrade method, which you have nothing to report here, you can just print to the screen a message “There is no grade here.”. This method will be overridden in the respective child classes. (iv) an equals method which compares two student objects and returns true if they…
