Write a C++ class and choose any name for it. The class should have two privatemembers and two public members. Write a constructor to initialize these membersto zero. Write another constructor to initialize these members to non-zero values.Write a method to return the average of the class members. Write a C++ programand initialize the members of the class with [2,5,8,3] respectively and call its methodto calculate the average.
1. Create a Student class that implements the Person interface. As well as storing the students name and email, also store their course grade (e.g A, B, C) in a member variable. The grade should be accessible via a getGrade method. For the implementation of getDescription return a message along the lines of “A C grade student”, substituting the students actual grade.2. Create a Lecturer class that implements the Person interface. This class should also store the subject that the lecturer teaches. Add a getSubject method, and implement getDescription so that it returns a suitable message, e.g. “Teaches Biology”.3. Create a third class, Employee that implements the interface. This should also store the name of the department the Employee works in (available via getDepartment). Again, getDescription should return a suitable message.

- In C++ Language using Functions and Pointers PROBLEM: Consider the elevator in the Faculty of Engineering (5 storey). Write a program which accepts the floor number where a passenger (student/faculty/other personnel) will ride the elevator. The passenger can then input the target destination floor. SPECIFICATIONS: Implement the class diagram below: Inside the main method, create an instance of the class Elevator. Use the goUp or goDown methods to generate the program display.Passenger can ride in any floor (1,2,3,4 or 5). Program will prompt the user with the target destination floor. After the user input: Program will display the floors which the elevator passes through, and finally the destination floor. Elevator will not move if the input for destination floor is the same as the present floor. Program will notify the user and then terminate. Program will also terminate if the input destination is not 1,2,3,4 or 5. You’re free to format the input/output display. Observe proper…arrow_forwardWrite in python and please include docstring. Write a class named Employee that has private data members for an employee's name, ID_number, salary, and email_address. It should have an init method that takes four values and uses them to initialize the data members. It should have get methods named get_name, get_ID_number, get_salary, and get_email_address. Write a separate function (not part of the Employee class) named make_employee_dict that takes as parameters a list of names, a list of ID numbers, a list of salaries and a list of email addresses (which are all the same length). The function should take the first value of each list and use them to create an Employee object. It should do the same with the second value of each list, etc. to the end of the lists. As it creates these objects, it should add them to a dictionary, where the key is the ID number and the value for that key is the whole Employee object. The function should return the resulting dictionary. For example, it…arrow_forwardPart (1) Define a class as follow: a. create a class called Student that has four instance variables - a (String) name, a (long) StudentID, a (String) College, and a (double) GPA. b. A constructor that takes student name, StudentID, College and GPA. The constructor sets the class variables to these values . c. Make the instance variable GPA private and provide a mutator method (set) and an accessor method (get) to access this variable. In set method if the GPA negative or grater than 4.00 print an invalid message and do not change the instance variable GPA. d. A method Student_Status () that check the GPA if it is less than 2, display the warning message, otherwise display Normal student. e.

If i have 4 Student objects how can i print the information for the specific object given one parameter about the class, like the students Idnumber. What i came up with was making a checkId void function that takes the user input and runs an if else chain checking if the Id belongs to student 1-4 then printing the details of that classes object with the void function print. ideally i would want the if-else chain in the checkId function to call the print( student1-4) class object but im not sure how to properly do that. i dont think this is the best way to go about it, if you have any recommendations or alternatives please help me out.arrow_forward
- Write the definition of a class Counter containing: • An instance variable named counter of type int. • An instance variable named limit of type int. • A static int variable named nCounters which is initialized to 0. • A constructor taking two int parameters that assigns the first one to counter and the second one to limit. It also adds one to the static variable nCounters. ● A method named increment. It does not take parameters or return a value; if the instance variable counter is less than limit, increment just adds one to the instance variable counter. • A method named decrement that also doesn't take parameters or return a value; if counter is greater than zero, it just subtracts one from the counter. • A method named getValue that returns the value of the instance variable counter. • A static method named getNCounters that returns the value of the static variable nCounters.arrow_forwardProblem C • -3: method consonants() had more than one loop • -3: method initials () had more than one loop • -3: at least one method used nested loopsarrow_forwardDesign and implement a data class. The class will store data that has been read asuser input from the keyboard (see Getting Input below), and provide necessary operations. As the data stored relates to monetary change, the class should be named Change. The class requires at least 2 instance variables for the name of a person and the coin change amount to be given to that person. You may also wish to use 4 instance variables to represent amounts for each of the 4 coin denominations (see Client Class below). There should be no need for more than these instance variables. However, if you wish to use more instance variables, you must provide legitimate justification for their usage in the internal and external documentation. Your class will need to have at least a default constructor, and a constructor with two parameters: one parameter being a name and the other a coin amount. Your class should also provide appropriateget and set methods for client usage. Other methods may be provided as…arrow_forward
- For C++ Programming II D.S. Malik Programming Exercise 10-16: Write the definition of a class swimmingPool, to implement the properties of a swimming pool. Your class should have the instance variables to store the length (in feet), width (in feet), depth (in feet), the rate (in gallons per minute) at which the water is filling the pool, and the rate (in gallons per minute) at which the water is draining from the pool. Add appropriate constructors to initialize the instance variables. Also, add member functions to do the following: determine the amount of water needed to fill an empty or partially filled pool, determine the time needed to completely or partially fill or empty the pool, and add or drain water for a specific amount of time, if the water in the pool exceeds the total capacity of the pool, output "Pool overflow" to indicate that the water has breached capacity. The header file for the swimmingPool class has been provided for reference.

The constructor should initialize the name 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's 10.0 34.0 2.0 1.0 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: Nutritional information per serving of None:…arrow_forward
