For C++ The following class represents a telephone number in the United States: enum PhoneType (HOME, OFFICE, CELL); class Phone { public: Phone(int newAreaCode, int newNumber, PhoneType newType); void Write() const; private: int areaCode; int number; PhoneType type; } We want to use inheritance to derive an international phone number class, called InternPhone, from the Phone class above. The InternPhone class needs to add a country code, represented as an integer, used to identify the country. The public operations the InternPhone class are responsible for are: Write() Reimplements the Write function from the base class. Paramaterized Constructor Requires four parameters. Write the class declaration for the InternPhone class. Provide an implementation for the InternPhone Provide an implementation for the InternPhone Write()

JAVA CODE Write a java set of classes that could be used to do simple calculations on geometricobjects. The set should include the following classes: a) Shapes ,containing abstract methods( a methods that is declared without animplementation) area and perimeter b) Rectangle, a subclass of Shape, containing a constructor (with parameters forlength and width) along with methods area and perimeter. c) Triangle, a subclass of Shape, containing a constructor (with parameters for the three sides of a triangle) along with methods area ( s = (a+b+c)/2, A = sqrt( s(s-a)(s-b)(s-c) ) ) and perimeter d) Square, a subclass of Rectangle, containing a constructor (with a parameter for thelength of a side) and methods that invoke the methods of the Rectangle class todetermine the perimeter and area of a square.
Define and implement a class named animal that has the following constructor and attributes: animal(string n, int v) ; // creates an animal with name n and body volume v. string name ; int animalID ; int volume ; // animals are allocated a unique ID on creation // the animal's name // the animal's unique ID // the volume of the animal's body Following the principles of encapsulation and information hiding, set the proper access modifiers for the attributes and provide methods to access the object's data. You need to set the name and volume of an animal, as well as get the animal's name, animallD and volume. There must not be a set function for animallD. The get and set function names should be the attribute name prefixed with "get_" or "set_" respectively. For example, the get and set methods for volume would be named get_volume and set_volume respectively. Declare the get_name function as pure virtual. When selecting between the three types of access modifiers for each of the…
In C++ create a program that acts like a bank account. That has 3 classes. The first class must be a generic class that holds basic info deposit, withdraw, calculate monthly interest rate, and a monthly service fee.The second class must be a savings account class that if the savings account falls below $25 it becomes inactive. The final class must be a checking account if someone withdraws more than what they have a service charge of $15 is added and go into a negative balance. The output should display the basic information how much someone deposited or withdrew and their monthly interest rate.
Define a new "Exam" class that manages the exam name (string) and its score (integer). For example, an exam can have - "Midterm Exam", 100 - "Final Exam", 50 The class must not provide the default constructor. It must require the exam name and score in order to initialize the Exam object. The class must provide only the following methods (no more and no less): - isPerfect method that returns true if the score is exactly 100 and false otherwise. - isPassing method that returns true if the score is equal or greater than 70 and false otherwise. - toString method must return all the exam information including the result of the exam as a string in the following format: EXAM(<name>) SCORE(<score>) RESULT(Pass/Fail) such asEXAM(Midterm Exam) SCORE(100) RESULT(Pass) EXAM(Final Exam) SCORE(50) RESULT(Fail) "Pass" means the score is greater or equal 70. "Fail" is whenever the score is below 70. - isGreater method that compares with another Exam object and return true if the score…

JAVA PROGRAMMING - Create a class named "Shape" that has rhe abstract methods getArea() and getPerimeter(). - Create a class named "Rectangle", "Square", and "Circle". Override the methods getArea() and getPerimeter() with the right equation in getting the area and perimeter. - For rectangle, create attribute length and width. For square, side. For circle, radius Inputs: 1. Char input for Shape Type (Rectangle, Square, Circle). 2. Dimensions for specific type of Shape Output: Shape: Rectangle Length: 10 Width: 50 Area: 500.00 Perimeter 120.00

In C++ create a program that acts like a bank account. It asks the user whether to deposit or withdraw. That has 3 classes. The first class must be a generic class that holds basic info deposit, withdraw, calculate monthly interest rate, and a monthly service fee.The second class must be a savings account class that if the savings account falls below $25 it becomes inactive. The final class must be a checking account if someone withdraws more than what they have a service charge of $15 is added and go into a negative balance. The output should display the basic information how much someone deposited or withdrew and their monthly interest rate.
Write C++ code for a class named MuniBus that has the following private member variables: int totalPassengers; double faresCollected; and the following public member functions: void passengerBoard() - adds 2.50 to faresCollected and adds 1 to totalPassengers double getFaresCollected() - returns faresCollected int getPassengers() - returns totalPassengers void reset() - sets totalPassengers and faresCollected to zero MuniBus() - default constructor. Initializes both totalPassengers and faresCollected to 0 MuniBus(int tp, double fc) - constructor which initializes totalPassengers to tp, faresCollected to fc ~MuniBus() - destructor. Prints out a message saying that the bus is being destroyed, and also prints out totalPassengers and faresCollected. Write the class declaration and implement all of the constructors, the destructor, and member functions. You do not need to demonstrate using your class or show output.
Define a class called token number that incorporates a token’s number (could be the last 3 digits of your arid number) and its location. Number each token object as it is created. Use two variables of the angle class to represent the token’s latitude and longitude. A member function of the token class should get a position from the user and store it in the object; another should report the serial number and position. Design a main() program that creates three token, asks the user to input the position of each, and then displays each token’s number and position.
