(Richer Shape Hierarchy) The world of shapes is much richer than the shapes included inthe inheritance hierarchy of Fig. 19.3. Write down all the shapes you can think of—both two-dimensional and three-dimensional—and form them into a more complete Shape hierarchy with asmany levels as possible. Your hierarchy should have the base class Shape from which class TwoDimensionalShape and class ThreeDimensionalShape are derived. [Note: You do not need to write any codefor this exercise.] We’ll use this hierarchy in the exercises of Chapter 20 to process a set of distinctshapes as objects of base-class Shape. (This technique, called polymorphism, is the subject ofChapter 20.)

(b) How does the static data member of a class differ from a non-static data member? Give a real-world scenario in which a static data member might be useful.

*Initial Class Diagram is attached below Refine the UML class diagram so that it demonstrates the following: Classes (using the complex class symbols), Associations (with multiplicities AND association names), Generalizations (if any), and Compositions (if any) Focus ONLY on the following activities within the system: Start a Trip, Reserve a Vehicle, Make a Parking Reservation, Make a Charging Session for a Personal Vehicle, End a Trip or Charging Session, and Submit a Support Ticket for a Vehicle or Station Add the primary key necessary to support any relationships that have a multiplicity of "1" as an attribute in the corresponding class

LANGUAGE : C++ QUESTION :  make a  class of Student with attributes StudentName, Enrollment, semester, section, course MarksObtained and Grade. Write appropriate constructors, get and set functions for data members. The data member grade is automatically calculated based on marks obtained out of 100 for each course. also print out the outputs

Game of Chess in C++ The objective of this assignment is to practice concepts related to inheritance, overriding, polymorphism, and abstract classes, to program the basics of a chess playing program. About: Chess is played on an 8 X 8 board where the initial placement of pieces. The white king is on e1, and the black king is on e8. Each chess piece can move in a specific way. Follow a simplified version. Most importantly, ignore an important rule in chess: Moving any piece in a way that puts your own king in check is illegal. Since we don't know what check means, for us a move is legal if the piece we are moving has an empty square to move to or can capture (replace) an opponent's piece (including their king). The king does not move at all. Nor can it castle the queen and knight can't move either. A pawn in the initial position may move one or two squares vertically forward to an empty square but cannot leap over any piece. Subsequently it can move only one square vertically forward…

SUBJECT: OOPPROGRAMMING LANGUAGE: C++ ALSO ADD SCREENSHOTS OF OUTPUT.   Write a class Distance to measure distance in meters and kilometers. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen.   Write another class Time to measure time in hours and minutes. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen.   Write another class which has appropriate functions for taking objects of the Distance class and Time class to store time and distance in a file.   Make the data members and functions in your program const where applicable

Nutritional information (classes/constructors) PYTHON ONLY Complete the FoodItem class by adding a constructor to initialize a food item. The constructor should initialize the name (a string) to "None" and all other instance attributes to 0.0 by default. If the constructor is called with a food name, grams of fat, grams of carbohydrates, and grams of protein, the constructor should assign each instance attribute with the appropriate parameter value. The given program accepts as input a food item name, fat, carbs, and protein and the number of servings. The program creates a food item using the constructor parameters' default values and a food item using the input values. The program outputs the nutritional information and calories per serving for both food items. Ex: If the input is: M&M's10.034.02.01.0   where M&M's is the food name, 10.0 is the grams of fat, 34.0 is the grams of carbohydrates, 2.0 is the grams of protein, and 1.0 is the number of servings, the output is:…
