In C++build a program to read that data with the following promptsa-) Create a class “name” with two data members: one for the first name (String) and one for the surname (String). The last name must be a pointer to char, the first name construct it as you prefer.b-) Create a grade class to store a subject name (String) and a grade (floating).c-) Create a class "student" that inherits from the class "name" and by composition can store the student's grades (consider that the maximum possible grades will be 6).d-) Create a group class to store the data of several students (consider a maximum of 10 students)e-) Develop a method that returns the average of the group of students.f-) Develop a method that returns the average of a student given his name and surname.g-) Develop a method that returns a list of students who have failed a subject (less than 6.0 points) given the name of the subject.h-) Develop a method that returns the first and last name of the student with the lowest…
Problem 1: Java programComplete the Clothing class, the class should have the following instance variables, constructor(s) and instance methods:- An instance variable of type double named price.- An instance variable of type String named type.- An instance variable of type String named size.- A default “no-arg” constructor that sets the price to 29.9, the type to “TShirt” and the size to “Medium”. - An overloaded constructor that takes three parameters and set the instance variables accordingly. - A method named increasePrice that takes no parameters and returns no value, the method increases the instance variable price by 5.- An overloaded method increasePrice that takes a double parameter xand returns no value, the method increases the instance variable price by the value of parameter x.- A method named details which takes no parameters, returns no value, the method prints the Clothing item details in the format shown in the sample output.- Your output should look exactly the same…
C++ Consider the following code: class A { public: virtual void printChar() { cout << 'A' << endl; } }; class B : public A { public: void printChar() { cout << 'B' << endl; } }; int main() { A a; B b; A *ptr; ptr = &a; ptr->printChar(); ptr = &b; ptr->printChar(); } Choose the best statement below: Consider the following code: class A { public: virtual void printChar() { cout << 'A' << endl; } }; class B : public A { public: void printChar() { cout << 'B' << endl; } }; int main() { A a; B b; A *ptr; ptr = &a; ptr->printChar(); ptr = &b; ptr->printChar(); } Choose the best statement below: a.) This code compiles, but has poor style. You shouldn't have a function printChar() defined in both classes. b.) This code compiles, and there is an example of polymorphism in the code. c.) This code compiles, and there is no example of…
Describe how memory allocation is done to objects and also develop a C++ programfor employee class with following attributes such as Employee ID, Employee Name,Designation and Salary. Program should sort and display the list of employees inascending order of their salaries using object as a function argument. (Note:Employee ID must not be inputted by the user i.e., auto incremented.)
Do all please. (a) Provide an example of a constructor method being overridden? (b) Describe Dynamic Binding as related to Class loading? (c) What is the role of a class loader? (d) What are two benefits of the Bytecode verification system?
Answer this in C++: In the Student.cpp file and Student.h file, build the Student class with the following specifications: Private data members string name - Initialized in default constructor to "Louie" double gpa - Initialized in default constructor to 1.0 Default constructor Public member functions SetName() - sets the student's name GetName() - returns the student's name SetGPA() - sets the student's GPA GetGPA() - returns the student's GPA Ex. If a new Student object is created, the default constructor sets name to "Louie" and gpa to 1. The output of GetName() and GetGPA() before and after calling SetName("Felix") and SetGPA(3.7) is: Louie/1 Felix/3.7 main.cpp #include <iostream> #include <vector> #include "Student.h" using namespace std; int main() { Student student = Student(); cout << student.GetName() << "/" << student.GetGPA() << endl; student.SetName("Felix"); student.SetGPA(3.7); cout <<…
using c++ define a class fruitType to store the following data about a fruit: Fruit name (string), color (string), fat (int), sugar (int), and carbohydrate (int). Declare a pointer of type fruitType to store the following data: Fruit name—banana, color—yellow, fat—1, sugar—15, carbohydrate—22. Write a member function, setFruitInfo to store data into a variable of fruitType. Write a member function, getFruitInfo to get data from a variable of fruitType. Write a member function, printFruitInfo to output data stored into a variable of fruitType. Use appropriate labels to identify each component. Test your solution by calling all funtions using the pointer.
Complete the missing programming steps correctly:1. class Base {public void Print() {System.out.println("Base");}}class Derived_______ Base {public void Print() {i.

Write a Program in C++ which completes following requirements:a. Create a class, having a static function printing some information and invoke that method using scope resolution operator.b. Try to access non-static data members from static method and write in comments what happens.c. Declare and initialize a static variable as counter in a function(increment it in every call) and call it multiple times printing the change in value
Kindly Solve this C++ question as per the instructions. Thank you for your help! Instructions: 1- Put the class definition in Flight.h and the implementation of the constructors and functions in Flight.cpp Implement the Flight.h and Flight.cpp so that class Flight contains: 4 private instance variables: Name of data type string, which describe the three electric vehicle charger types (AC975, DL521, and AC863). Destination of data type string that shows the final destination of that flight. Hour and Minute of data type int that show the departure time. A default constructor which sets all of the numeric instance variables to zero and the String instance variables to null. A constructor with 4 parameters that sets the 4 instance variables to the corresponding values passed. Implement an accessor method for each information (Flight name, Flight destination, and Flight Time) that will return the value of the instance variable. For example, the getX() method for the instance variables…
