- IN JAV1. Declare a class called country that contains a function called language that prints "English" Define 3 classes and they all inherit from country A brand named Australia A class named Saudi Rewrite the language function and change the implementation of the function so that it prints "Arabic" A class called Spain Rewrite the language function and change the implementation of the function so that it prints "Spanish" Build a Test class to test the code with the Main function and then create objects of the three classes that Workshop of the father's class Then call the language function The result should be as in the picture English Arabic Spanish(Combining Class Time and Class Date) Combine the modified Time class of Exercise 17.7and the modified Date class of Exercise 17.8 into one class called DateAndTime. (In Chapter 19, we’lldiscuss inheritance, which will enable us to accomplish this task quickly without modifying the existing class definitions.) Modify the tick function to call the nextDay function if the time increments into the next day. Modify functions printStandard and printUniversal to output the dateand time. Write a program to test the new class DateAndTime. Specifically, test incrementing thetime into the next day.C++ : Define a new class Fighter that inherits from the Spaceship class below. - Add a private member variable: int firePower; - Create a default constructor which initializes firePower to 10 and initializes name to "X-wing" - Create a member function in Fighter void warp(). This function should increase position by 10, and decrease health by 5. - Redefine function wasHit(). Instead of decrementing health by 5, decrement it by 2. class Spaceship { protected: string name; int health; int position; public: Spaceship() { name = ""; health = 100; position = 0; } void moveLeft() { position--; } void moveRight() { position++; } void wasHit() { health -= 5; } };
- write a c++ in which you vreate a class Point. This class have four member variables, a,b,c,d. Write the following member functions drawTriangle(int x, int y, int z ) and drawRectangle(int x, int y, int z, int a). Each function should calculate the length of lines and calculate circumference for each of the shape (triangle, rectangle). example triangle should calculate length of its three lines and then calculate circumference. such as, Note: the number of lines depends on the name of shape.void drawTriangle(int x, int y, int z ){int line 1 = x - y; // convert to positive value if line 1 is negativeint line 2 = y -z; int line 3 = z -x; cout<< the circumference of triangle is << //// here write formula to calculate circumference of triangle and display output of circumference}Write similar code for drawRectangle(int x, int y, int z, int a). write main function to callthese three functions to display output.b. write another function drawLine(int x, int y) in the above code.…Hi, I am having trouble with this homework question for my C++ course 1.

Assign appropriate access modifiers to insure encapsulation.d. Add a private calc GPA() function that calculates and returns the GPAbased upon the two exam grades.e. Add a public getGrade() function that: 1. Obtains the GPA from the private calc GPA() function.2. Returns a letter grade based upon the numerical GPA value.90 to 100 = A80 to 90 = B70 to 80 = C60 to 70 = D0 to 60 = F f.

- plz do it urgent in devc++. and plzz dont reject it Define a pure abstract base class called BasicShape . The BasicShape class should have the following members: Private Member Variable: area, type double used to hold the shape's area. Public Member Functions: setArea: assigns received argument to area variable. getArea. This function should return the value in the member variable area. calcArea. This function should be a pure virtual function. Next, define a class named Circle . It should be derived from the BasicShape class. It should have the following members: Private Member Variables: centerX, type integer used to hold the x coordinate of the circle’s center. centerY, type integer used to hold the y coordinate of the circle’s center. radius, type double used to hold the circle's radius. Public Member Functions: constructor—accepts values for centerX, centerY, and radius. Should also call the overridden calcArea function described below. getCenterX—returns the value in…Cr3ate a class named Person, use the __init__ () function to assign values for name and age class Person: def __init__(self, name, age): _______________ _______________p1 = Person("John", 36)print(p1.name)print(p1.age)Q2: Using C# - Class Account declares two instance variables, name and balance. Class SavingAccount derives from Account and declares an instance variable minBalance of type double.
